So if acetone worked, I suppose methanol would be even better? (assuming zinc carbonate is not very soluble in methanol.)

Also, did anyone prove whether a manske could separate thh (hydrochloride) from zinc or if it would be stay in solution like the quinazolines.

And, I wasnt sure about the formation of zincate salts under high pH conditions. Does that happen or is it still speculation?

I did read all endlessness' thread this time, and the other thh separation thread which uses ammonium chloride, but it seemed like no definite conclusions were reached.

One last thing, Ive noticed zinc supplements being sold in health food shops, so maybe ingesting small amounts of zinc is harmless or even beneficial?
