德国Uhde公司在德国法兰克福举行的Achema(化学设备展览会)会议上介绍了由Degussa和Uhde开发的以过氧化氢(H2O2)为原料生产环氧丙烷(PO)的HPPO新工艺,并宣布了采用此新工艺的首家用户。该工艺无副产物及含氯废弃物,更具经济性。目前采用传统氯醇法生产的PO约占PO总产量的50％,剩余50％则采用共氧化法生产,这两种工艺都产生大量的联产物。 German company Uhde presented the new HPPO process for the production of propylene oxide (PO) using hydrogen peroxide (H2O2) as raw material developed by Degussa and Uhde at the Achema conference in Frankfurt, Germany and announced the adoption of The first user of this new process. The process has no by-products and chlorine-containing waste, more economical. At present, the PO generated by the traditional chlorohydrin method accounts for about 50% of the total output of PO, and the remaining 50% is produced by the co-oxidation method, both of which produce a large amount of co-products.
