改进合成草酰氯工艺条件的确定

The Establishment of Technological Operation of Synthetic Oxalyl Chloride

对文献中草酰氯合成工艺进行了改进 :改变反应物的配料比 ;将反应物同时溶入三氯氧磷中使其充分混合 ;反应过程中控制温度并不断搅拌。实验结果显示 ,产品的收率提高近40 % ,反应时间缩短至 1 0h。

The technological operation of synthetic oxalyl chloride is re-established by the experiments in contrast with old the technological.The new technological operation shortens the reaction time and the productivity is increased.
