       Hash extraction and isomerisation in acetone?  Bookmark   

I've read about hash-oil extraction and isomerisation in TFSE,
but I had the idea that acetone might bee used instead of IPA,
would this work?

First put ground-up hash in a cup (we're not talking big
amounts here) and then fill it with acetone and then put a
"lid" on the cup and swirl it around several times each
day for a week. Then add a few drops of H2SO4 the last
day and let the acetone evaporate.

Would this work at all? Only reason I ask is beecause
acetone is available and "why not".smile

As I said before, acetone will extract not only the THC but also a lot of crap out of the weed.

       yeah ok  Bookmark   

but I still smoke all that "crap" when I smoke the hash as-is,
so it's not that bad. But will that "crap" make it difficult
to isomerize the oil?

Seems you were very right Megatherium, and I think anyway
that IPA/MeOH (thank Bob for anti-freezewink) would bee a
better solution. Or solvent, as it were.

But how long shall I let the hash soak in IPA/MeOH beefore I
distill? Seems there are some contradicting opinions about it,
one says just soak for 5-6 hours and evap, while others
have said let it soak (with stirring) for days.

Also, this is 100% kitchen chem, no glassware or other
fun equipment available right now, keep that in mind when
answeringwink

You don't want to smoke acetone extracted hash,trust me,you don't.Get some dry ipa or something completely non-polar like hexane or CO2
For those about to synth,we salute you

       thc extraction  Bookmark   

Dichloromethane is good both for the extraction of THC's from hash (just reflux/boil and then filter of the sawdust), and for the subsequent isomerization with TsOH (or maybe H2SO4). Neutralization/Washing/Drying/Evaporation gives an oil which is very trippy and not that soporific.

Good tip Rhodium!smile

I'm still looking for a good source of H2SO4 where I live,
so the isomerisation is put on the back-burner for now.

Due to lack of equipment I doubt I'll try the DCM route now,
but I'll try when I have a better possibility to distill
off DCM from paint-stripper or whatever I can find.

AFAIK IPA/MeOH is my best choice right now, out of all the
solvents that are available at least.
