【Abstract】 Dissociation extraction is a unique technique for separating mixtures of organic acids or organic bases. Its research and application has spread into the fields of extraction and separation of chemical substances from coal tar oil, polyphenols, substituted phenols, amines, alkaloids and herbicides. It is also used in separation of products in the pharmaceutical industry. Recent research advances in the dissociation extraction process are described. Separation factors of dissociation extraction and their influencing elements are analyzed. Criteria for selection of extracting agents and solvents in dissociation extraction are also pointed out.更多还原
