Applications

Hexachloroethane is used as catalyst in preparation of chlorosilanes from hydrosilanes. It is also used to investigate the transformation of hexachloroethane in natural waters and as reagent during polycondensation reaction of p-aminobenzoic acid. It is used as a source of chlorine in the chlorodehydroxylation of alcohols in the presence of triphenylphosphine.

Notes

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Incompatible with strong bases and strong oxidizing agents.
