Title: acetone-water/ tartaric extraction
Post by: catfish on July 09, 2003, 04:27:00 PM
Hi all-
so SWIM has these MG seeds and ground up 26 g to a powder. The flour was defatted with 2X50 mL tetrachloroethylene, filtered and dried. Extraction with 5 g tartaric acid in minimum of water and ~150 mL acetone followed; portion wise, 20 mL at a time, filtering with cotton and washing the cotton with last 10 mL. Evaporation so far has yielded a yellow fluid, growing viscous VERY gradually, with some xtals forming, most likely excess tartaric acid. More later.

Title: acetone and TCE are miscible
Post by: catfish on July 10, 2003, 12:23:00 PM
B-
the main reason SWIM waits for the flour/ pulp to dry is that the residual TCE is miscible with the acetone.
So far, only sticky oil has turned out.
Oil was taken up in IPA, and poured into ~6 oz of 24% **** in the dark. We will see what the morning brings...

Title: SWIM had the same result, dense gold brown...

SWIM had the same result, dense gold brown fluid with a strong fruitly smell. But was too much "spicy" due to the tartaric, wish to know how to deal with the acid, should add some ammonia drops, or use NaHCO3?
