I guess Gotta never had to learn..
You know, it must be nice to be like that. I have had sucess, and I have thanked you people. If you called me a "Little punk," well, bite me. I have nothing but respect for this forum, and I know the difference between polar and non. I had a specific question on Acetone. I am glad you were endowed with the knowledge, and never had to have it explained. You probably always knew that it was kinda both, being very unique.
Would you answer a question. What are the best temps to reduce eph via rp/i? What are the paramaters. And don't be a jerk. I have cut and pasted things you have said to my notebook. Thanks.

Re: I guess Gotta never had to learn..
Sure as shit, there is no reference to those punks in that thread. I was speaking to kirby in a way that he would understand, not realizing that it could easily be misconstrued by the author of the thread as being directed toward him. I apologize. It went right past me.
Dude, don't feel too bad about ripping me up when you reread the post and realize that the direction of my comments were specifically toward neversleepy and treephrog. They both intentionally try to piss me off and sleepy and I go way back.
Sometimes, I snap back at these punks not realizing whose thread I am in. This has occasionally caused the author of the thread to be offended thinking I was referring to them. I don't know why I let them get under my skin. Just the other day I was saying something to tired and kirby about sleepyfrog getting to them and now I let those fucks compromise my position among the ones who truly attempt to be decent to those with at least halfway decent questions. My intentions are always to sincerely try to help anyone who is willing to help themselves and do it to the best of my ability.
Now, with that said, I must admit that I can be quite sarcastic when making a point. I also can pour a little frustration onto someone who doesn't deserve it. Hell, I'll have to go and see what you are talking about. Maybe I really did piss in your cornflakes, but for a fact
IN NO WAY WERE THE COMMENTS THAT CONTAINED THE WORD PUNK DIRECTED TOWARD YOU.
Furthermore, if I really was shitty toward you and you did not deserve it, you have my sincere apology.
If it was the dry acetone dissolving pfed question, I learned that and everything else in three places by committing many long hours of research to further my understanding of one specific project, the rp/i.

Re: I guess Gotta never had to learn..
This is what switrd emulates...with a few personal tweeks.
The idea is to get the reaction going in the most controlled way possible. Now you want to let reagents react in the icebath, if at all, Then move vessel from icebath to room temp, If things look like they're going too fast, put back in ice bath, You want to keep the reaction going but only at a nice slow, controlled pace! This is also necessary to control vapour in the condenser! Thick and or dis-colored smoke is bad! and plumes of smoke will escape from condenser As things progress at a nice slow pace, as things slow too much you can start applying heat! So prepare an oilbath and bring to about 50c, now if there is no more action in your vessel You can move it to the oilbath, and same as before, when things slow down, Adjust heat up, to say 100c then 150c for one hour, to make sure reaction has completed.
Are you finished?: Your reaction flask is full of larger bubbles and those small ones you have watched for so long are missing. When you remove the flask from the heat, and the flask cools enough the contents cease boiling, you should see no small bubbling activity. If the smell you already recognize is present add some hot water to the flask. If you are not too sure about the smell, add a little hot water, careful not to flood the reaction out. (Geez adds as much hot water as there is fluid in the flask at this point if the smell is right.) The red phosphorous should fall out of the solution right away. When the flask cools just enough for the convection currents to cease, swirl the flask and watch how fast the red phosphorous falls to the bottom. If it stays in suspension or does not completetly settle, or if the red slowly drifts to the bottom and the fluid is reddish orange, put it back on the hot plate and let it cook some more.
This has been brought to you in part by LwaysTired....and was found in and at Rhodium's. Thanks to them.

Re: I guess Gotta never had to learn..
I've always liked that old dickhead, Osmium over at the hive. He is a real bastard, but he really makes you think. I have always felt very strongly about two things concerning this reaction.
1. If it is truly possible to complete an rp/i reduction reaction in a couple of hours, it cannot be done without enough water and/or heat.
2. Too much water dramatically increases the amount of time needed until completion and the reaction can be a complete failure simply by adding too much water.
Swigotta has not yet been able to prove number one wrong, but he has proven it right several times now, varying different parameters each time. He now refuses to waste any more time on it.
Number two has never been tried, only hypothetically evaluated based on the ratios of others and Swigottas successes using these ratios.
This has changed. I convinced Swigotta to use the proper amount of water in a reaction. I asked for the cleanest of everything for the experiment and he reluctantly agreed. When the calculations were done and the water was determined to be just a hair over 2mls. per gram of pseudo, he said no way. So, I had to compromise. It's ridiculous, but here's what I did. I know that on small batches he likes to go with Geez and 0.7mls/g., the general rule is 1.0/g., sleepy says use 2.0mls/g., and the reaction scheme called for 2.?mls./g.(I forgot exactly). I averaged them and came up with 81mls instead of the 109mls originally denied. He still thought it would be a total waste of time, money, and good clean precursors.
After explaining the importance in regard to theory versus practical knowledge, he finally agreed.
Since we both believed that a "textbook" reaction was just not going to happen, I wrote in something that Os had written concerning the initial addition of reactants.
1. Finely ground rp
2. chopped up pseudo (just so it will pour into the flask ok)
3.DH2O
Now, mix this up pretty good, get a rubber stopper that fits the flask, and begin to slowly add the iodine. Add it in 10-15% increments, stopper the flask and swirl and mix. Let it cool off just a little at first before adding some more. Let cool progressively more as you go. Do this until all is added to the flask. You will get some heat, and the stopper may pop when removed on the last few additions, but no smoke,no excessive temps. This part worked out very well and Swigotta decided to add that to his procedure. The rest I've already said somewhere else. Basically it is too much water. Stoichiometric amounts of water would have blown the reaction. Even with the 81mls, it required varying the temp up, removing the stopper from the top of the condenser for a while, and freaking out and adding more iodine close to the end. 61 hours and it only gave up about 21g. from 52g. That's only about 40% (w/w). It was really good though.
The temp? For the long haul- 90-100C. The quicker you go the hotter you must go. The hotter you go, the more side reaction, byproducts,and undesirables you will create. That's with pill pseudo of any degree of cleanliness. I guess usp ephedrine would create much less side reaction byproducts. I don't know. Anyway, longer is better, or that's what my wife says.

Re: I guess Gotta never had to learn..
agrees with gotta. from hands on, in the field research i might add. 2ml per gram of E would take in theory 4 to 6 days and thats if it dont flood the rxn. my opinion, but i know nothing. also gotta i must say i like the idea of adding the E/RP/DH2O to flask 1st followed by DH2O then I2 in small increments untill all is in. what better way to control the rxn. makes sense to my one brain cell. sometime it takes awhile for the light to come on but when it does its fuckin bright. and one more thing i might add, i have to agree with sleepy on one thing and thank him for making me think. in the lava lamp rxn (which SWIM believes will work most excellent) he says to take a lighter and coat the bottom of the rxn vessel with soot to lessen the amount of photo energy into the rxn. makes good sense to me since i was already puzzling over the same thing every since beebo at CH2 made my mind start to think about it. it is the general concensus that photo energy introduced into the rxn will cause free radicals to form in the iodine. beebo advised that one reconfigure the lamp base to accept a standard base bulb like an ordinary household bulb uses instead of the small base bulbs the lamps use normally. then take a black light party bulb and screw it in to the lava lamp base. the temp is perfect and the black light reduces dramaticly the photo energy introduced into the rxn. make sense? does to my single brain cell. im thinkin ill soot the bottom and use the black light bulb. any thoughts? gotta, sleepy? is the sooting needed with a black light bulb? and do you think that if nothing else the sooting will make the glass heat more evenly eliminating hotspots?

Re: I guess Gotta never had to learn..
Wrap the bottom of your "flask" with heavy duty aluminum foil.
Somebody run some temps on this thing. A light bulb should apply even temps once the heat dissipation maxes out. Well, as long as there is no air circulating.
My better half thinks its such a cute idea. Sounds like a bunch of modifications to me.
Here's the same idea:
potpourri heaters. They have a small thin wire element in them with no resistors or thermostat. They only get up to about 135-145F though. Maybe fewer modifications than the lava lamp. All you gotta do is twist another element with a few more turns of wire. Pretty easy.

Re: I guess Gotta never had to learn..
all you long wet cookers SUCK!!! I am going to start a fast cook gang to battle you long cook bastards. we will duke it out in the streets with steal pipes and chains while we throw down our gang signs.
really though i guess its just a matter of personal opinion really, cause i like dope that was cooked fast and hot a WHOLE lot better than wet and long. the short cook shit has a lot more fireworks and euphoria, thats for damn sure. even if it does have more byproducts..... the buzz makes it all worth it. the long cook dope always feels like desoxyn to me with is boring and no fun in my books.

Re: I guess Gotta never had to learn..
acidmelt.....actually switrd was browsing around in a search and found what he thinks to be the "classic" Slacker Reaction. As of yesterday he has a friend preparing for the party. He says he's going to make some modifications and use some of his personal preferences. Like the solvents used. So I'll write back if all goes well. Come to think of it...I'll probably write back if all goes terrible too.

Re: I guess Gotta never had to learn..
Acidmelt--
Since I have been the main one beatin' the piss out of the short hot lately, perhaps you could take a few minutes to outline this technique for me with perhaps some notes where there are critical processes to consider.
It is truly a mystery to me why Swigotta is so terribly unsuccessful with this mehod, while boneheads like shooter can pull it off. (just kiddin shooter)
He has learned the long reflux and is in the process of fine tuning his technique in order to maximize the Q and Q.
From a newbee perspective, the long has better odds of sccess considering the huge factor that overall cleanliness of precursors adds to the success/failure rate. The low temps are the predominate factor governing success with substandard precursors.
Who knows, maybe Swigotta's precursors were not of adequate quality at the time he was experimenting with the short cook.
At any rate, I would really like to put this issue to rest in my mind.
If you had something you could PM me at the hive or CH2 it would be great. Maybe I will stop criticizing that fucked up method if it was proven to work through Swigotta.
I wish I could find a way to get over the memories of chemhead and get back over there. I'm having trouble with depression when I see the screen layout. It drags my thoughts back to what was going on at the time I was there last.
You guys didn't need to know all that. I'm a fuckin psycho but fuck it. Who cares?

Re: I guess Gotta never had to learn..
for sure ill share some things that SWIA has noticed to be key features. I dont have time right now, but I will do it tonight. and that is totally true, I would like to have those crystals on my mirror right now instead of 3 days from now, I guess I am not very patient. Actually I knwo Im not. It always drove SWIA crazy to wait things to filter so he bought a vaccum filtration setup. much faster.

Re: I guess Gotta never had to learn..
This is precisely the point when it comes to learning the short. We all know what its like to look in the bottle and think of the miracle whip commercial. Then start digging through old pipes looking for residue (well, only smokers do this. Shooters dig for rinse bags and snorters look for mirrors and straws). There just isn't much motivation to fire up a 3 day run. No sense in watching that pot till it boils.
Who wouldn't want to be like AM, Jacked, and Worlock. (pretty good company, eh, AM). Throw it all together, blast it for an hour. Cool, clean, and base. Fluff it out, filter, dry, enjoy. Whole thing 2-3 hours. And thats mostly dependant on your post rxn. experience level. Now thats pretty attractive.
I remember reading where a guy's ass was draggin, so he whipped up a short, hot batch to get him motivated so he could get his long reflux goin.
This makes it important to have this technique "under the ole belt" so to speak.
AM, I truly understand time constraints. I really should be able to figure this thing out. Your help will be appreciated, but not expected. You've always been a good dude. Never read anywhere that you were shitty to a legitimate inquiry.
That is honorable, grasshopper........or is it danielsan?

Re: I guess Gotta never had to learn..
lol- short and hot? try long wet and hot.
or cool(150 degrees f) and long somewhat dry.
lol... actul scientific equation could determine when and how long 100% meth can be acheived but I forgot some of ussis tryin to cook in a plastic jug. lol.....
lye itself would burn a hole through a plastic jug,,, don't take nasa to figgure that out for ya llol
210 degrees fahrenhight with just enough water and whatever time you like seems reasonable,,,notice whatever you like.
if your heating this at a temperature to evin
begin byproducts, SwiG wouldn' like that obviuosly,
so why not 135 F? why not never bring it above 150F, guess temp and time is relative to what your are trying to accomplish lol.
compromise sucks when the best is what you want. lol-

150f at the beginning, then slowly bring it up to 180f, over a 25 minute period. The rxn should last bout 45-55 minutes. The "pull" takes about 25 minutes.
