摘　　要：工业用环氧丙烷GB/T 14491-2015颁布实施后,下游聚醚客户对环氧丙烷质量要求更高。通过优化氯醇法环氧丙烷工艺降低环氧丙烷产品总醛质量分数,满足客户需求。Propylene oxide GB/T 14491-2015 for industrial use has been promulgated and implemented,and downstream polyether customers have higher requirements for the quality of propylene oxide. Optimize the process of propylene oxide by chlorohydrin method,tackle key technical problems,reduce the total aldehyde content of propylene oxide products,and meet customer needs.
