摘要

Abstract

Developing of non-metallic catalyst to replace metal catalyst is a meaningful and challenging direction. In this work

the non-metallic catalyst was synthetized successfully by loading ionic liquid onto the silica surface

which was applied for the gas-phase dehydrochlorination of 1

2-tetrachloroethane. The 12%TPPC/SiO

(wt%) showed the best results with the conversion of 1

2-tetrachloroethane reaching 100%. The selectivity of 1

2-trichloroethylene was 100%

and no deactivation was found during the evaluation period. The catalytic mechanism was investigated and possible reaction route was given

which was a reference for fabricating and design of solid base catalyst.
