Benzene hexa chloride

Benzene hexachloride - C6H6Cl6 What is Benzene hexachloride? Benzene hexachloride is an isomer of hexachlorocyclohexane with a chemical formula C 6H 6Cl 6. It is also known as Lindane or hexachlorane. Benzene hexachloride is a colourless solid with a slight musty odour. It is an organochlorine chemical and is widely used as an agricultural insecticide as well as a pharmaceutical treatment for scabies and lice. Some side effects of lindane are burning, stinging, or redness of the skin. In the year 1825, Faraday was the first person to originally synthesize this chemical. In the year 1942, a Dutch chemist Teunis van der Linden isolated Benzene hexachloride. He was the first one to describe γ-hexachlorocyclohexane in the year 1912. Its pesticidal action was discovered in 1942. Table of Contents • • • • • Preparation of Benzene hexachloride • Chlorine combines with benzene, in the presence of sunlight and in the absence of oxygen as well as substitution catalysts, to form hexachlorocyclohexane. • Lindane can be prepared from chlorine and benzene by photochlorination. The product obtained i.e benzene hexachloride comprises isomers from which only the gamma-isomer is wanted. Gamma-isomer is got by treating the reaction mixture with acetic acid or methanol in which only the alpha and beta isomers dissolve easily.

Benzene Hexachloride An organochlorine insecticide that has been used as a pediculicide and a scabicide. Benzene Hexachloride has been banned in California, United Kingdom, Australia, and many western countries due to concerns about neurotoxicity and adverse effects on the environment. In Canada, Benzene Hexachloride is not recommmended as a first-line therapy due to reports of resistance, neurotoxicity, and bone marrow suppression, but has been approved by the FDA as a second-line therapy for topical treatment of pediculosis capitis (head lice), pediculosis pubis (pubic lice), or scabies in patients greater than two years of age who cannot tolerate or have failed first-line treatment. Benzene Hexachloride is still allowed for pharmaceutical use until 2015. Scabies is a common, highly pruritic infestation of the skin caused by Sarcoptes scabiei (lice). It is a very contagious condition with specific lesions, such as burrows, and nonspecific lesions, such as papules, vesicles and excoriations. The typical areas of the body it affects are finger webs, scalp (hair), wrists, axillary folds, abdomen, buttocks, inframammary folds and genitalia (males). It is characterized by intense night-time itching. Scabies is spread through close personal contact (relatives, sexual partners, schoolchildren, chronically ill patients and crowded communities). Scabies infestations and the corresponding symptoms can be eliminated by killing the scabies with topical insecticides or scabicides. Be...
