Influence of Supporting Silica Gel on the Catalytic Activity of B-18 Crown Ether-KCl Complex for the Selective Dehydrochlorination of 1,1,2-Trichloroethane

Article abstract of DOI:10.1246/bcsj.58.1589

Catalytic dehydrochlorination of 1,1,2-trichloroethane into 1,1-dichloroethylene proceeded selectively around 200 deg C over dibenzo-18-crown-6-KCl complex supported on silica gels.The reaction rate depended very much on the kinds of silica gel and impregnation levels of the complex, suggesting some roles of surface hydroxyl groups in this catalysis.
