Perchloroethane

Hexachloroethane [67-72-17, perchloroethane, CCl CCl, is a white crystalline soHd with a camphorlike odor. Hexachloroethane is nonflammable and has a number of minor industrial uses which are limited because of its toxic nature. Crystalline hexachloroethane is a minor product in many industrial chlorination processes of saturated and unsaturated hydrocarbons.

Solvent additives to the melt (Table 3) fall into two categories extractive and reactive. The extractive solvents (decane, perchloroethane, o-dichlorobenzene, and pyrrolidine) had negligible effect on solubility, possibly due to the preferential wetting of the coal by the solvent and exclusion of the ZnCl2 melt. Reactive solvents (anthracene oil, indoline, cyclohexanol, and tetralin) all incorporated strongly. Donor solvents, tetralin and indoline, increase the "corrected solubility, whereas anthracene oil and cyclohexanol have negligible effect. 

Hexachloroethane is a colorless solid that gradually evaporates when it is exposed to air. This compound is also called perchloroethane, carbon hexachloride, and HCE. It is sold under the trade names Avlothane, Distokal, Distopan, and Distopin. In the United States, about half of the hexachloroethane is used by the military for smoke-producing devices. It is also sold as degassing pellets that are used to remove the air bubbles in melted aluminum. Hexachloroethane may be present as an ingredient in some fungicides, insecticides, lubricants, plastics, and cellulose. At one time, hexachloroethane was prescribed for deworming animals.

The chemical exploration of perchloro-organic chemistry was initiated early last century by the almost simultaneous discovery of three chlorocar-bons perchloroethane, perchloroethylene and perchlorobenzene (Faraday, 1820 Julin, 1821 Muller, 1862, 1864 Phillips and Faraday, 1821a,b). In spite of its early, rather sudden, start, this chemistry remained almost dormant until the second third of the current century. 

Neither molecular chlorine nor perchloroethane was detected. However, minute amounts of the perchlorostilbenes were found (0.6% of total), thus supporting the intermediacy of PB-. 

It is noteworthy that this chlorination can be effected using carbon tetrachloride as the chlorine source under the influence of ultraviolet light. This result is traced to photolysis of carbon tetrachloride, which is known to give chlorine and perchloromethyl radical (photochlorinations in carbon tetrachloride invariably give small amounts of perchloroethane owing to dimerization of CCI3 ).
