【Abstract】 The deep eutectic method with hydrogen bond formation between phenols and hydrogen bond acceptor for extraction of phenols from coal tar has the advantages of low energy consumption,low pollution and high efficiency. The research progress of extraction and separation of phenols by deep eutectic method in recent years has been reviewed. The main factors affecting extraction efficiency,the recycling of extractant,the mechanism and theoretical development of extraction are analyzed and summarized. The problems of deep eutectic method are pointed out and the development trend of deep eutectic method is proposed.更多还原
