acetone-water/ tartaric extraction | Bookmark | |||||
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. -catfish all information related for educational purposes only! no quarter asked, none given |

acetone and TCE are miscible | Bookmark | |||||
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... -catfish all information related for educational purposes only! no quarter asked, none given |

SWIM had the same result, dense gold brown... | Bookmark | |||||
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? Nevermore!! |
