Camphorlike odor

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. 

Dicyclopentadiene has a camphorlike odor with a 100% recognition threshold of... 

Hexachloroethane has a camphorlike odor, readily sublimes, and, when heated to decomposition, emits phosgene. Sublimation of hexachloroethane may contribute to exposure control problems. Sedimented hexachloroethane dust may accumulate on fluorescent mbe illuminators and other warm surfaces and act as an exposure reservoir, adding to exposure levels. ...

The first daughter plasma product of CCI4, hexachloroethane, is colorless solid with a camphorlike odor that sublimes at 189°C. It has also been identified as a human carcinogen. C2Clg acts primarily as a central nervous system depressant, resulting in narcosis in high concentrations. 

Olfactory impressions are of course very individual and depend on the experience of the worker. An odor can be characteristic of a whole class of substances in one case, and in other cases only of a certain limited group of substances (the smokey odor of medium alcohols). Sometimes two completely different compounds possess an almost identical odor (for example, the camphorlike odor of hexachloroethane), and very often the odor changes even in a homologous series (lower, medium, and higher aliphatic alcohols or acids).
