Abstract

HEXACHLOROCYCLOHEXANE was synthesized by Michael Faraday in 1825. This chemical compound was obtained in a condensate from the compression of oil gas. Van der Linden, after a century of accumulative work by other investigators, established the identity of four isomers and their melting points.

The insecticidal properties of hexachlorocyclohexane were studied by Thomas in 1942. He employed a sample of the crude product against the turnip flea beetle, but subsequent samples gave variable results. Pure alpha, beta and gamma isomers were then synthesized from the crude compound and used against weevils. The final analysis provided the conclusion that the alpha and beta portions were relatively nontoxic and that the gamma isomer was the active insecticidal agent. The gamma isomeric fraction is 10 to 12 per cent of the whole crude hexachlorocyclohexane and is referred to as gammexane.®1
