First, use distilled water, it's cheap, readily available, and free of contaminants. Second, shouldn't you be using about three times as much NaOH?
believe it or not it was enough. No emultion what so ever. and my solution was a DEEP DEEP DEEP black color.
and tap water works good enough. Im not going for a super pure crystal, just something that will get you off in a bind.
and to get the naphtha layer off Iv just used a "plastic" turkey baster. I tested it by leaving naphtha in it over night then leaing the naphtha on my evap tray to evap. No residue left behind which would (to my limited knowledge) show that it didnt leach anything from the baster.
BTW the extraction I did took less then 6 hours! no idea on the yield yet as I am freeze/preciping now. This was brazilian MHRB so I suspect at most .5g.
And this was the first extraction Iv done this way, in larger extraction Iv used 250g of naOH per 2000ml. which still gives you a high enough PH. Granted this sint the absolute best method for a clean product but it is the best for a quick extract. L8ter tonight I'll test it out and see how potent it is.
and I prob added closer to 75g of NaOH, as I didnt get the heat desired from the 50, but it wasnt any more then maybe a full spoons full.
ANYONE can do this extraction, and its relitively safe seeing as at the NaOH step you have 500ml to work with.
