General description

Effect of hydrogen peroxide concentrations on the degradation of hexachloroethane in the absence and the presence of tetrachloroethene by Fenton′s reagent has been investigated.

Application

Hexachloroethane was used as catalyst in preparation of chlorosilanes from hydrosilanes. It was used to investigate the transformation of hexachloroethane in natural waters. It was used as reagent during polycondensation reaction of p-aminobenzoic acid.
