日本住友化学公司开发了无任何副产物的环氧丙烷生产路线。该工艺采用一种专有的钛基环氧化催化剂 ,可使丙烯环氧化成ＰＯ的收率大大提高。其最大优点是不产生任何副产物 ,装置布局简单 ,比传统工艺具有明显的成本竞争优势。新工艺改善了ＰＯ生产的灵活性 ,且不受苯乙烯市场需 Sumitomo Chemical Japan has developed a propylene oxide production line without any by-products. The process uses a proprietary titanium-based epoxidation catalyst, propylene epoxidation can greatly improve the yield of PO. Its biggest advantage is that it does not produce any by-products, the device layout is simple, and it has a significant cost competitive advantage over the traditional process. The new process improves the flexibility of PO production, and is not required by the styrene market
