高纯碳酸丙烯酯的精馏工艺研究

Study on High-purity Propylene Carbonate Rectifying Process

以工业级碳酸丙烯酯为原料,重点研究再沸器、二丙二醇含量、真空度及回流比对高纯碳酸丙烯酯的品质及收率的影响,总结出最佳的精馏工艺条件。

The industrial-grade propylene carbonate as raw materials, primarily use the different types of reboiler, dipropylene glycol of different purities, vacuum and reflux ratio to effect the quality and yield of high purity propylene carbonate, summed up the best process conditions of distillation.
