Default Geez's i2 extraction method and Modified Curbshot Recipe

I cant find Geez's i2 extraction method. I read Lukky pasted it in a thred a while ago searched and no luck. Also read Gottagogo gots the modified curbshot recipe and he pasted it in tadpoles thread lokked through threads for the last year and also no luck. Could someone help me out. Thankz

This works:

Ratio for nano rp/i

Pseudo(ephedrine)=1

RP(really clean mbrp)=0.6 (soso clean)=1.0

Iodine (from 2%tincture)=1.5

decent small rb boiling flask (500ml)

heating mantle would be nice, but oil bath on hot plate will do.

large balloon (the kind with a rubberband attached for kids to bounce it on their hand)

twist ties and don't forget DH2O, the D means distilled, NO SUBSTITUTES.

Add RP to flask followed by pseudo(ephedrine) both chopped up (rp ground up finely).

Add DH2O, amount depends on who you ask. You wanna go dry, use .5 ml. per gram of Iodine. You wanna go long and wet, use 1.0ml. per gram of Iodine.

The recommended DH2O for the long, wet is now .7ml. per g. pseudo. Maybe. (There is no short. It was added to keep the hotheads from going ballistic.)

Mix.

Get your balloon ready and add the Iodine (dry iodine EXTRACTED and very DRY) to the mix.

If done properly you should get a rxn producing white smoke relatively soon, so get that balloon attached. Secure the balloon with twist ties tightened tightly around bolloon and flask.

Cook it slowly (if long, slow is chosen) with only a few bubbles on surface of liquid, for about 12 to 30 hrs. Longer the better. If short is chosen, bubbles should cover the surface, not too vigorous, and cook for at least 3-6 hrs.

Post rxn. you Gotta find out yourself.

*********************************************

If you are pouring your based reaction fluid down the drain, you are wasting resources and polluting the sewers. (Well, I hope its the sewers and you aren't just pouring the stuff out on the ground to leach into the water supply. That would be environmentally irresponsible).

As hard as I2 can be to come by its a shame to toss out easily recoverable I2, and if you are not reclaiming the Iodine from the based reaction fluid, you are throwing usable precursors away.

When SWIG lets his post-reaction fluid sit, it usually precipitates white needle-like crystals which are water soluble, particularly in hot water. These are sodium iodide crystals. There may be some NaOH in there, but I doubt that these are NaOH crystals, since NaOH is still soluble in the solution they form in.

These NaI crystals can sit there for months. SWIG has never seen I2 crystals form in the reaction fluid on their own...but has seen these NaI crystals form almost a solid mass in the storage container. Maybe SWIG is doing something he should not, or not doing something he should. In SWIG's experience Iodine forms as I2 in the based post reaction fluid if the solution is neutralized with H2SO4 and an oxidant added to the solution. SWIG uses 3% H2O2.

Here is how he does it:

he filters the sodium iodide crystals out of the reaction fluid using a piece of high thread count sheet as a filter. These cannot be rinsed in water, as they will dissolve. These are placed in a gallon jar, and diluted H2SO4 is added slowly. (Always use diluted acid for this, as straight acid kicks, spits, fumes, and reacts violently. Dilute sulfuric is much safer and easier to use.) The NaI crystals will dissolve instantly in dilute acid. SWIG tries not to add too much H2SO4, adding just enough to neutralize the solution and make it slightly acidic, but with dilute H2SO4 the difference between pH 9 and pH 4 is a few drops. It takes a lot to neutralize the base, but when the solution foams, you are at or past neutral, depending on how much acid you just added. When you see the first sign of foaming, you should assume you need to add acid just a few drops at a time until the mixture is neutral. SWIG uses an old pH meter to check pH. He is happy if he has a pH of 5 to 6. If SWIG overshoots and gets the solution too acidic, he adds some more of the based reaction fluid to bring the pH up. (This is also why he uses a gallon jar...since he is from the bigger hammer school of fixing things...)



Frankly, he assumes that having the pH a little acidic is what he should do. He has done this with very acidic solution with success, but seems to have no success when the solution is basic to neutral. He lowers the pH based on assumptions made from what worked for him, and not on a theoretical understanding of what is going on. (Feel free to point out the errors of his ways.)

SWIG pours in 3% H2O2, while stirring, but adds it slowly. When the solution turns a turbid dark brown he stops adding peroxide. You can't even shine a light through it. He leaves the jar as is and does something else. He is patient, and just leaves the stuff for the next day.

The next day the I2 that has precipitated is at the bottom of the gallon jar. SWIG decants the fluid, which by now is dull and the color of tea the ice has melted in. He puts a fine cloth (220 thread count sheets make great filters for this purpose, and one sheet makes a bunch of them!) in a funnel, puts the funnel in dismembered solar tea jug (a reminder of his push pull days) puts the hole in the solar jug over the drain, and pours the water used to rinse the I2 through the cloth, into to the solar tea jug, which lets the excess water drain out where the spigot was, but allows any I2 which gets through the cloth to collect in the inch of water in the bottom of the jug to be reclaimed later.

Do rinse this I2 even more than you do the I2 from tincture. It not only has trash from the acid and base and their reaction, it has trash from the 12/rP reaction, and may have waxes or oils, or even some spilled tequila in it. Get it clean. Then clean it again. The treat it like I2 from tinture. Compress it, dry it, use it.

Actually, the best way to clean I2 is to resublime it.

Save it to a disk or something as threads and posts tend to get lost.

Hey Gotta....gotta say (whoah four of em little dots that time hehe)...good post...A couple of quick questions tho... Swirh had researched the "resubliming" a ways back and decided that he would prob have a QT tan from all the damn fumes and that it sounded messy as hell. He is keenly interested in the quality of the I2 after Dh2o washes? Is it weaker than I2 from tinc? Or do ya have to go up some on the ratio? And would scalding/very hot water help?? Swirh jus doesn't like idea of the industrial sized crack pipe and a fan with the shit fuming all around... He read somewhere that I2 can kill a person in from 2 hours to 52 days... Little joke there...<so you are on day 34 huh?> hehe.

He realized that that was direct ingestion of straight I2 but he don't take lightly the thought of deadly toxins (shudders when he thinks of the "old" days). But this way seems to be much messylessness and very applicable. Thanks for the help and keep up the good work man... Peace...

The entire post was saved stuff. I only wrote the last line. Swigotta still can't seem to make geez's iodine reclaimation work and I can't find out what he's doing wrong except measurements. If you don't know how much is in there, how can you know how much peroxide to put in? Anyway, I guess washed tincture is ok, but Swigotta just recently started resubliming the iodine he gott from 2% tincture and will never again use anything less. It's not what you think. There are no fumes flying around. The worse is maybe a little eye burning, but Swigotta says he gets that when he washes tincture. Easy as hell, too.

The wife says lets go right now. Since I've been pecking for a couple of hours, I guess I'd better go. I'll tell ya what the savant has been doing with that iodine when we get back. If I could just figure out a way to get that phosphorous acid, Swigotta will have obtained Zen.

Default Re: Geez's i2 extraction method and Modified Curbshot Recipe

this is from a email he sent me .

here you go gogo . copy it

============================================

Use per liter of 7% tinc 25 ml HCl (37%) (not critical, use some, use enough, a little more will not hurt.) add 500 ml water, add with stirring, one liter 3% H2O2

Or since you are american, a pint of tinc, a pint of peroxide, a cup of water and a shot glass of acid. Stir well, let it sit. Let it sit. Give it four hours at least.

Decant the fluid into another jar and rinse out the crystals in the bottom of the first jar real well, 5-6 times with lots of swirling. I filter through a piece of bedsheet and get all the crystals in there and mash real well, dry good, transfer to fresh coffee filters, put in a jar that has epsoms salts (dried) in the bottom, put a folder paper towel in, the sit the crystals on top. Try to dry the crystals as best you can to start..but come back and change the coffee filters after about four hours, the next day, etc...after two changes, the I2 is generally dry. If you react them still wet, use 1.5 gm instead of 1.2 and decrease the water in the reaction by 20%.

Leave the solution in the second jar, add about another 125 ml of peroxide and let sit until the next day. You will get another batch of crystals, up to 25% as much as before, usally about 10%.

Works fine. On a good batch you can get up to 50 gm of I2 from a pint. Usually you will get 43-46 gms. A lot better than the one ounce I used to get with three bottles of peroxide.

question...i guess i'm a little confused! would you add the water per g of iodine or the psuedo?

SWIL always used a water:Phed ratio, rather than iodine. He was always taught 1 ml to 1 gram, will need a reaction of 30-36 hours+, at 185 degrees Farenheit.

I was looking for something and ran across this. Sorry, late answer.

There are as many different ratio combinations as there are people who know what Madonna looks like naked.

I read that since HI is produced by the combination of iodine and water, the ratios should be between them. It makes sense, doesn't it?

So what! Who cares if it makes sense? It just doesn't pan out.

Geez came up with the 0.7ml. recently for nanos to minimize reaction time.

So what! Who cares? Cook it longer.

Like lukky says (have you noticed yet that its always just like lukky says?) the best way to go is pseudo to iodine 1:1.

Chemically speaking this may be wrong. Practically speaking, it works best.
