摘　　要：解离萃取是分离有机酸或有机碱混合物的一种特殊技术 ,该技术的研究应用已涉及到煤焦油、多元酚、取代酚、胺类、生物碱、除草剂中化学物质的提取与分离以及医药工业中产物的分离。本文综述了解离萃取过程的研究进展 ,分析了解离萃取的分离因子及其影响因素和解离萃取中萃取剂。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.
