Default Question about my cold water extraction

2 Questions: I did a cold water extraction of codeine from some 222's (OTC caff/cod/apap pills)

1.) is their away to further seperate the codeine from the caffeine?

2.) Can this liquid be evaporated into a powder? If I cooked it on really low heat for a long time, would that work, or would it destroy the codeine?

Thanks to anyone who answers my question

Hello?

Anybody?

C'mon, someone must have an answer for this question. It's not THAT stupid of a question, is it?

Maybe it is, I don't know.

if you had a roto evaporator you could evaporate off the caffine--or vice a versa
