二异丙醚催化合成的研究进展

Research Progress of Catalytic Synthesis of Diisopropyl Ether

二异丙醚(DIPE)是重要的原料和溶剂,广泛用于化工、环保、制药等方面。由于具有高辛烷值和良好的抗冻性能,DIPE也可用作汽油混合剂。但是,对用于合成DIPE的催化剂的研究及其应用工艺的开发仍处于初期阶段。综述了合成DIPE的几种催化剂,主要有无机酸、蒙脱土、离子交换树脂、沸石等,并介绍了其应用的具体工艺。

Diisopropyl ether(DIPE)is an important raw material and solvent,which is widely used in chemical industry,environmental protection and pharmaceutical industry.Because of its high octane number and good frost resistance,DIPE can also be used as gasoline mixture.However,the research and application of catalysts for the synthesis of DIPE are still in the initial stage.Several catalysts for the synthesis of DIPE are reviewed,including inorganic acid,montmorillonite,ion exchange resin,zeolite,etc.,and the specific application process is introduced.
