是关于手性拆分的,万分紧急,
Selective Extraction of d-mene with d-Tartaric Acid:
amines were resolved with 0.5 mole tartaric acid in benzene-water containing 0.5 mole sodium hydroxide or potassium hydroxide by selective extraction of either enantiomer.
A mixture of mene base in 60 ml benzene,0.05 mole d-tartaric acid (7.50 g.) in 30 ml water,and 2 g sodium hydroxide (reagent grade or titrated equivalent) in 3 ml water was kept 4 hours with intermittent shaking,and the organic phase evaporated to give 98% L-mene.The aqueous phase was extracted with benzene at pH 13 and evaporated to give 96% D-enantiomer.
