纤维素醇解制备乙酰丙酸酯的研究进展
Research progress in preparation levulinate esters by alcoholysis of cellulose
摘要
Abstract
Levulinate esters is a kind of high value-added chemicals that could become a new generation of biofuels or fuel additives through alcoholysis for the utilization of cellulose resource.This paper reviewed the recent research progress of the preparation of levulinate esters through alcoholysis of cellulose under the conditions of acid catalysts systematically,and focused on introducing the catalytic effect of several kinds of catalysts researched in the filed such as inorganic acids,solid acids,mixed acids,and ionic liquids.The advantages and disadvantages of these catalysts were summarized.The mechanism of alcoholysis was discussed as well as the different catalytic role of Lewis and Bronsted acids in the process of cleavage of glycosidic bond,isomerization from glucose unit into fructose unit,and further conversion of fructose unit into levulinate.The existing problems in the research of alcoholysis,such as harsh reaction conditions,low selectivity,unclear reaction mechanism were discussed.The future research directions of studying the details of cellulose alcoholysis mechanism and designing and synthetizing catalysts with higher activity and selectivity were pointed out.关键词
