The separation of traditional Chinese medicine extraction equipment castor acid methyl ester was conducted with methanol and castor oil methyl ester exchange for a quick castor acid. Acid methyl ester exchange reaction products contain about 85% castor oil, the rest of methyl oleate, methyl oleate, methyl stearate, and the mixture of dihydroxy methyl stearate, collectively known as mixed ester, including dihydroxy methyl stearate easily after crystallization separation, while the rest of the methyl several commonly used liquid liquid extraction separation.
the separation of traditional Chinese medicine extraction equipment castor acid methyl ester with castor acid methyl ester containing a hydroxyl group and some more water than mixed ester, the two mutually miscibility and polarity within different organic phase, the several kinds of ester distribution coefficient is different, with hexane as the alkanes, extraction experiment in the laboratory, the experiment observed the event phase mass transfer rate soon, in less than 5 minutes can reach balance, therefore this extraction process in industry to achieve more easily.
