1. Production Process
Propylene Oxide (PO) is the third largest propylene derivative next only to polypropylene and acrylonitrile. The production technology mainly includes chlorohydrin and indirect oxidation. Due to the serious environmental pollution of chlorohydrin, China has already stopped the examination and approval. Domestic indirect oxidation process equipment all adopt foreign technology. But now, Ruihua has developed the first set of PO/SM co-generation process technology in China.

The process includes four parts: ethyl benzene peroxide, epoxidation, benzene ethanol dehydration and phenylacetone hydrogenation.
