摘　　要：环氧丙烷与苯乙烯共氧化法是目前生产环氧丙烷的常用方法之一,共氧化法环氧丙烷工艺过程中会伴随化学性质活泼的中间产物和一系列副产物生成。这些物质在生产过程中含量过高,会降低装置的安全性并且增加运行成本。通过近红外分析仪器在装置中的应用,就可以随时确定该组分的含量,从而保证装置安全高效的运行。Propylene oxide(PO)and styrene monomer(SM)Coproduction method is one of the common methods for the production of PO product.But during the production of PO,a series of reactive intermediates and byproducts are generated,high level of these substances in the process can reduce plant safety and also increase operating costs.By this paper,it is illuminated that the content of such substances can be determined at any time by using NIR analyzer,thus ensuring the safety and efficient of plant operation.
