Not getting 80% of the E back as Meth by weight?

It is not surprising, but the reasons are not what you would expect.

First of all, generally, the stuff is being produced in the reaction, it is the recovery and cleaning phases that are killing the good yields.

To recover an additional 15%-30% of your product takes some time, and a lot of work, it is not quick.

Another problem is it is lost in various different solutions making it confusing and complicated as to what was what, especially if you have saved everything including the ephedrine powder on through to the final product.

One way to get a 5% to 20% of your shit back is simply keep your lye water and water wash solutions, put them in a big jug, blast them with more NaOH get it up to pH13 - pH14, add toluene shake it very well, let it sit for 24 hours, go back pull off the toluene and any whitish emulsion layer. Forget the brown emulsions(too nasty). Wash this three(3) times with small amounts of d-water, about 1/4 the volume of the Toulene solution. Smaller multiple washes are more efficient than larger washes.

Add HCl (don't gas) you will be surprised to find quite a bit. It is not the cleanest but if you save it after a few batches you will have a substantial amount that is worth the effort to clean up.

Add to the above all Acetone washes after evaporating the acetone and your looking at another 5% to 25% depending on the brand of acetone you use, most acetone contains water and some contains benzene, and other chemicals, warm acetone can dissolve large amounts of your product.

How often to you treat the speed with acetone while still warm?

Plenty of times, if your like me.

Another thing about acetone is it will dissolve away Meth-HI salt, which is always present in varying amounts.

A final source of easily recovered lost product will be in the alcohol left over from recrystalization, it is saturated with meth, and full of toxins also. evaporate the alcohol and add it to the pile of recovered speed.

These three sources is where you can make a 50% return into an 80% return.

Filters of all types suck up dope like a sponge, wash them out in alcohol and discard them , evapoate the alcohol.

After you have collected enough of these spare bits and pieces, maybe from several batches, then clean them up.

Grind them to a powder,

wash with cold acetone

Recrystallize with a dry alcohol like methanol or a good denatured. Some denatured is full of everything under the sun MEK, Benzene, Acetone , and water, this is no good for your purposes.

The simplest method is to boil a little methanol or denatured or dried isopropynol in a vision ware bowl, with a fan blowing on it to prevent fire. Pour in your go-go retun to a boil. Add enough alcohol to dissolve all the speed. If the mixture appears cloudy consider adding more alcohol and filtering it first.

Once everything has dissolved, boil the alcohol off until

A skin begins to form on the surface.

Cover the bowl and place it in the freezer for ten to twelve hours. The longer in the freezer the better and the bigger will be your crystals. It is hard to tell just by looking at the surface of the crystals, in the bowl, but once you pull them out and dry them you will definately tell the beneficial effect, that longer times have upon this process. Since the alcohol does not freeze it continues to digest and reform the crystals of meth, this purifies them and grows them larger.

Quickly break up the chunks and place in a filter, vacuum filters are the best because less time involved.

As the solution warms up it will dissolve more dope, so you want to filter it and dry it as as quickly as possible.

Place the damp crystals on a sheet of paper to help draw out more of the fluids as quick as you can. Then let the crystals air dry to evaporate away any residual solvents for an hour or more. This will have cleaned out the toxins, and recovered a large pile of lost dope.

I told you it took a while and is somewhat labor intensive, but if you consider the difficulty in obtaining E, you may find that the 15% - 30% extra return is worth the effort.

Then again you might say screw it and cook up another batch.

Since it takes 2-3 days to complete the process, this is not for everyone.

Thanks Jam......

Another great write up!

End advice is ALWAYS handy to have!



BCT

try wetting your filter paper before use,,this stops the eph molecule being absorbed to the core of the paper.

many say the slow evap with no heat,, just a fan,,, stops the loss of eph through evaporation, though all techinical data states it will not evaporate until approx 170c

after the birch,,when you add the hexane to the solid in the reduction vessel,,then filter it,,separate the quenching water from the np,,,evap the quenching water till theres only a very dry solid left,,,now add toluene to the solid and leave a day as jam suggested,,,,

whats in the filter,,clean 3 times with dnh2o and titrate...

wash bottle with a bit of metho and evap metho,,whats left add to filter meth for titration....

another way to save your gear is give the fucker a slap who heats it in the pipe to much,,though the best way ive found to save your gear is not to invite the freeloading buggers at all,,keep it all for yourself...

any of those rumors about giving the reaction double the time and shaking it up post reaction true? I hear people going back and forth "if you have to shake you didn't mix wel enough or just were't patient"

what reaction

what reaction

red-p/iodine

have i missed something,,,

isnt this thread about maximising pseudo yields....

no, this thread is about getting back 80% of your ephedrine weight back in meth.

yes your right,

see what drug abuse does to you wicked..

hold on,

i wanna hear of everyones opinion of picking up the flask of red/iod/eph and giving it a good fuckin shake for awhile whilst cooking.

then ask whom gave such valuable advice.

mmm, swim would shake it if it was a wild ass reaction to calm it, lmao.

and hell ya to cleaning all filters with warm dh20 or alchol, let dry ona plate in dust free spot n scrap ur fri night dinner.

ohhh and PS, to max yeilds be sure to gas 30 to 45 sec , filter, regas 30sec, filter and regas.. swim pours all gassed np into a large jar,,, save a day n gas again.

rxn,

commercially,

you can evap the np,

titrate anything there,

and its finished,

thats the last job,

pack it all up,

hide it,

and bugger off

you just dont wish to be in the hotseat another day waiting....

SWIM swirls his flask while the cook is happening. not at any time interval just when ever he walks by or not. doesnt hurt anything.

yep swim does the same, keep it from stickin or anything

roger that kirb swim agree's with ya.
