Mg/SiO2 catalysts are active for dehydrochlorination of 1,1,2-trichloroethane.
Catalysts with Mg(NO3)2·6H2O and MgCl2·6H2O as the precursors had identical performances.
A high yield of cis-dichloroethene (83.7%) was obtained on a stable 10Mg(N)/SiO2−300 catalyst.
Mg(OH)Cl is regarded as the active site for the reaction.
