一种耐酸性的碱性催化剂及制备方法和应用
摘要：
本发明公开了一种耐酸性的碱性催化剂及制备方法和应用。所述碱性催化剂由载体以及负载在载体表面的活性组分组成，所述的载体使用SiO2、TiO2、SBA‑15、活性炭、TS‑1、MCM‑22中的一种或者多种,所述的活性组分是以卤素离子作为阴离子的离子液体中的一种或几种的组合,所述的卤素为氯或溴,所述活性组分的负载量(活性组分/载体)为0.10％‑45.0％。本发明提供了所述碱性催化剂在1.1.2‑三氯乙烷气相脱氯化氢制偏二氯乙烯的反应中的应用。本发明提供的催化剂具有寿命长、活性高的优点。
摘要（英）：

The invention discloses an acidic-resistant alkaline catalyst, and a preparation method and an application thereof, wherein the alkaline catalyst consists of a carrier and an active component supported thereon. The carrier includes one or more of SiO2, TiO2, SBA-15, active carbon, TS-1 and MCM-22; the active component is a combination of one or more ionic liquids with halide ions being negative ions, the halide being Cl or Br. The supporting load of the active component (active component/carrier) is 0.10-45.0%. The invention also provides an application of the alkaline catalyst in a reaction of gas-phase dehydrochlorination to 1,1,2-trichloroethane to produce vinylidene chloride. The catalyst is long in service life and high in activity.
