摘要
以聚合级D-乳酸为原料,辛酸亚锡为催化剂,对D-丙交酯的合成工艺进行了探索。分别考察了搅拌速度,聚合时间,聚合温度对D-丙交酯粗品产率的影响。用气相色谱仪对D-丙交酯粗品中各组分的含量进行了分析,用微量水分测定仪对D-丙交酯的水分含量进行了测试。
The synthesis of D-lactide by use of polymer grade D-lactic acid as raw material and stannous octoate as catalyst wasstudied.The impacts of stirring speed,polymerization time and temperature on the yield of crude D-lactide was observed respectively.The contents of each component in crude D - lactide are analyzed by gas chromatograph,and the moisture content in D-lactide istested by KF Titration Meter of Trace Moisture Determination.
