Description

white crystalline solid Heptachlor is an organochlorine cyclodiene insecticide isolated from technical chlordane. It is available in the form of white crystals or a tan-colored waxy solid with a characteris- tic camphor-like or cedar-like odor. It is sparingly soluble or insoluble in water, but fairly soluble in acetone, benzene, ethanol, xylene, and other organic solvents. It is used for the control of termites, ants, and soil insects in cultivated and non-cultivated soils. Heptachlor epoxide

Heptachlor Use and Manufacturing

Methods of Manufacturing

Chloridine is synthesized from hexachlorocyclopentadiene and cyclopentadiene, and then chloridine is further chlorinated to make heptachlor.

Uses

Formerly as insecticide for control of cotton boll weevil.
