Chinese medicine extraction equipment gaa extraction process
Industrial gaa extraction technology in traditional Chinese medicine extraction equipment is directly from the wool cotton oil gaa, medicinal gaa quality requirement is high, more than from cottonseed extract, using 80% in gaa with larger solubility and cottonseed oil solubility in acetone smaller this characteristic, with 80% acetone on cottonseed solid-liquid extraction (
, get contain gaa more extract, then using traditional Chinese medicine extraction equipment after the extraction of cottonseed oil for further processing.
Chinese medicine extraction equipment gaa solvent extraction process based on aniline reverse extraction to the extract.
Free gossypol with aniline generate aniline gaa, which makes the crystallization precipitation.
After separation, the aniline gaa suspending in the ether, add dilute sulphuric acid is free gossypol, and precipitation with ethyl ether to generate acetic acid gossypol.
