摘要
采用三氧化二铝作催化剂催化乳酸脱水,讨论了丙交酯制备过程中的影响因素,用重结晶法得到了高纯度的丙交酯,并通过熔点、红外光谱对丙交酯进行了表征。
The influencing factors were discussed in the preparation of lactide using Al 2O 3 as catalyst to carry out lactic acid dehydration. The lactide of high purity was obtained by the method of recrystallization and identified by melting point measurement and IR.
