大部分环氧丙烷新增产能建立在环氧丙烷和苯乙烯单体或 MTBE联产的基础上。人们认为这种方法在成本上低于较老的氯乙醇路线。然而 ,苯乙烯单体贸易是周期性的 ,而MTBE在美国前景不明 ,联产品市场难以预测的变化 ,给采用联产方法的环氧丙烷业经营者带来难题。如果有低成本、无联 Most of the new propylene oxide capacity is based on propylene oxide and styrene monomer or MTBE co-production. It is considered that this method is less costly than the older chloroethanol route. However, styrene monomer trade is cyclical, and the uncertain outlook for MTBE in the United States and the unpredictable changes in the co-product market present problems for propane propylene oxide propane co-production operators. If there is low cost, no joint
