高纯丙交酯的合成研究

生物可降解聚乳酸的实验表明：乳酸→丙交脂→聚乳酸中丙交酯的合成质量对聚乳酸的聚合是关键的。与同种催化剂相比，改进了合成方法，探讨了合成影响因素，缩短了反应时间，提高了丙交酯的质量。

Study on Synthesis of High Quality Lactide

Polylactide,a biodegradable polymer, is an important biomedical meaterial. The synthesis of lactide from lactic acid is the key dimer of polylactide,unevitably affacting the polymerized process and the quality. Present work improves synthesis process of lactide. The synthesized factors are discussed, the reactive time is shortened and the quality of resultant is also raised.
