摘　　要：聚乳酸是目前应用最为广泛的可降解材料之一 ,丙交酯是由乳酸制备聚乳酸的中间体 ,其产率偏低是制约聚乳酸大规模应用的关键。对乳酸合成丙交酯近 2 0年来的现状作了比较全面的回顾 ,包括乳酸合成丙交酯的主要方法、工艺及影响丙交酯产率的主要因素。Polylactic acid is one of the most promising biodegradable polymers, lactide is the intermediate for the preparation of polylactic acid from lactic acid ,the conversion of lactideis low and hamper the extensive application of PLA. In this paper, the present study for lactide synthesis from lactic acid has been reviewed for the past two decades, including the main methods of the synthesis of lactide from lactic acid, process and factors to influence the yield of lactide. Based on these, several methods of improving the yield of lactide have been brought forward.
