Hey,SwiM was wondering, he's pretty sure he's fucked a cook up & that the fuck up occured at the basing part(is that titrating?) of the workup.

His Q is; if he throws everything back into the container-this is curbs nano BTW, he plans to return to the part where the RP has been filtered off & the lighter fluid has been added- what ph must the NP be at?

When the lye is added is it the polar layer which needs to be ph checked?

Since he's gonna have to track down some ph strips anyway, he might as well ask, when adding the HCL, what ph is required?

Again, is it the polar layer that needs to be checked.

Many thanks guys.

Yes it is the polar layer that needs to be checked, you can't pH a non-polar layer anyhow. There is no way to make non-polar solvents acid or basic.

Hey, tryp. Thanks.

Masahed, the np is not to be checked for ph,

but the dh20. If using the sep funnel, you will be checking the bottom aqueous layer, not the np. Lighter fluid in, now add lye/dh20 mixture in which will drop to the bottom of the layers. Gently swirl or shake gently for 3-5 minutes. Ph the bottom layer

till 13 or 14. Let sit for 20-30 minutes, then seperate layers, sitting the dh20 aside.

Give a few hot dh20 baths to the np. Now you

have washed np. Add half as much fresh dh20 to np. Take hcl and eyedrop the ph down to 5-6, testing the bottom layer. Always ph the

aqueous or bottom layer

after each drop of hcl. Save your

bottom layer and evap

Excellent, ta dude.

Heh, finally realised WHY it's called NON-polar!

Sorry Masahed, Tryp had answered while I was typing! Good luck dude!!!

Remember, you cannot overbase. Too much base will simply make it more of a chore to clean up your end product. Also, titrating is the part where you add the hcl and convert the freebase to the salt. If you know how much freebase needs to be converted, you can calculate exactly how much acid is needed.

If you guess at about 50% conversion of original pseudo weight and add 3 drops of muriatic (1 drop of conc. hcl) for every 1/10th of a gram estimated meth, you will probably get pretty close. The titration is also hard to screw up. Lets say you estimate that there is about 10 g. of meth in the funnel. 30 drops (1ml.) in some DH2O will pull the "cream" off the top, so to speak. Thats the part you save for yourself. You don't even have to recrystallize if you don't want to. After that, you just go in there and do it again until the evap plate produces no more crystals (or meth crystals anyway).

I could be wrong, but any unreduced pseudo seems to come over in the last plate. If you think about it, this is a good way to separate good, ok, and so-so or mine, yours, and theirs.

Eat all we can and sell the rest!

no wonder you have nervous cattle over there str8

Ta gotta, he's not holding out much hope, but SwiM thinks this mess may just be salvageable.

Hope so.
