1,2,3,4,5,6-헥사클로로사이클로헥세인 화학적 특성, 용도, 생산

• 화학적 성질

  BHC is a white-to-brownish crystalline solid with a musty, phosgene-like odor.

• 용도

  Insecticide.

• 정의

  An environmentally persistent constituent of a wide variety of agricultural, medical, and veterinary products.

• 일반 설명

  White to yellow powder or flakes. Musty odor. The gamma isomer is known as lindane, a systemic insecticide. Toxic by ingestion or inhalation.

• 반응 프로필

  Halogenated aliphatic compounds, such as HEXACHLOROCYCLOHEXANE, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Materials in this group may be incompatible with strong oxidizing and reducing agents. Also, they may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

• 위험도

  Highly toxic; questionable carcinogen.

• 잠재적 노출

  The major commercial usage of BHC is based upon its insecticidal properties. α-BCH is used as an Agricultural chemical, pesticide, pharmaceutical, and veterinary drug. The 7-isomer has the highest acute toxic ity, but the other isomers are not without activity. It is gen erally advantageous to purify the 7-isomer from the less active isomers. The γ-isomer acts on the nervous system of insects, principally at the level of the nerve ganglia. As a result, lindane has been used against insects in a wide range of applications including treatment of animals, buildings, humans for ectoparasites, clothes; water for mosquitoes; living plants; seeds and soils. Some applications have been abandoned due to excessive residues, e.g., stored food stuffs. By voluntary action, the principal domestic producer of technical grade BHC requested cancellation of its BHC registrations on September 1, 1976. As of July 21, 1978, all registrants of pesticide products containing BHC voluntar ily canceled their registrations or switched their former BHC products to lindane formulations.

• Carcinogenicity

  A bioassay of lindane of the NCI was published in 1977. The compound was administered for 80 weeks to groups of Osborne–Mendel rats and B6C3F1 mice. Time-weighted dietary levels for male rats were 236 or 472 ppm; for female rats, 135 or 270 ppm; and for male and female mice, 80 or 160 ppm. Results were as follows: in rats, no tumors occurred at a statistically significant incidence in the treated groups of either sex but (2) in mice, the incidence of hepatocellular carcinoma in lowdose males was significant when compared with that in the pooled controls (controls 5/49, low dose 19/49, p = 0.001). This finding, by itself, is insufficient to establish the carcinogenicity of lindane. The incidence of hepatocellular carcinoma in high-dose male mice was not significantly different from that in matched or pooled controls. It is concluded that under the conditions of this bioassay lindane was not carcinogenic for Osborne–Mendel rats or B6C3F1 mice.
  As with most other chlorinated insecticides, lindane has been shown to exhibit tumor promotional activity, possibly via inhibition of intercellular communication. Lindane exposures do inhibit formation of liver tumors following exposures to aflatoxin B1, suggesting an activity other than tumor promotion for lindane. Enhancement of enzymatic deactivation of aflatoxin via induction of microsomal enzymes may play a role in this phenomenon.
  The combination of lindane’s lack of significant mutagenic activity, its tumor promotional properties, and the lack of epidemiologic evidence suggest that lindane poses a minimal to nonexistent risk of cancer to humans under reasonable and prescribed use conditions.

• 비 호환성

  Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explo sions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Decomposes on contact with powdered iron, aluminum, zinc, and on contact with strong bases producing trichlorobenzene.
