Codeine
« on: May 12, 2004, 09:06:00 AM »
swim did some research but only to find that codeine will come through an A/B. (not to sure how true this is)
Does anyone know of a way to remove codeine from pseudoephedrine?

orh i forget to mention its Codeine Phosphate. If the phosphate is anything like the sulfate, one gram dissolves in 1300ml of alky, then pulling the pseudo with cold alky might be enough to do the trick. If anyone has info on the phosphate derivative it would be greatly appericated. im trying to find info myself but not having alot of luck.

no a/b

It would bee important to remove the Codeine before a/b'ing these pills (if one was going to a/b). Because I think once its turned into free base and mixed with the FB PFED then it would probably be very difficult to seperate.

I just learnt here

https://rxsecure.umaryland.edu/courses/PHAR535/lecture_handouts/Liquids/Liquids_Lec_Handout.pdf


that 1gm of codeine phosphate is soluble in 325mLs alcohol. This means you would have to dissolve your pfed/codeine in 6.5mLs of alcohol and filter it to get the codeine out (all but 20mgs would be left.) Like as if you could do that  ::)
