Progress in Production Technology of Propylene Oxide With Molecular Oxygen as Oxidant

（上接2007年第2期） 2.7 用承载的Pd作催化剂 村田和久等人介绍了一种用Ti-MCM-22和Pd化合物的混合物作催化剂,使丙烯与O2在液相中反应来生产PO的工艺[28].

The process for production ofpropylene oxide by propylene direct epoxidation method using molecular oxygen as oxidant is introduced in detail. The direct oxidation methods include integrated method,oxygen direct oxidation method and hydrogenoxygen direct oxidation method. The catalysts used in each process are introduced and the advantages and disadvantages of each method are compared.
