베타-헥사클로로시클로헥산 속성

베타-헥사클로로시클로헥산 C화학적 특성, 용도, 생산

화학적 성질

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

물리적 성질

Although β-BHC is a solid at room temperature, the odor threshold concentration is 0.32 μg/kg (Sigworth, 1964).

용도

β-1,2,3,4,5,6-Hexachlorocyclohexane is an organochloride which is one of the isomers of hexachlorocyclohexane and is also an byproduct of insecticide Lindane (L465990).

정의

ChEBI: The beta-isomer of hexachlorocyclohexane.

일반 설명

Colorless crystals. Corrosive to aluminum and many other metals.

공기와 물의 반응

Slightly soluble in water.

반응 프로필

Halogenated aliphatic compounds, such as BETA-HCH, 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. Dehydrochlorination occurs in the presence of alkalis.

건강위험

ACUTE/CHRONIC HAZARDS: Highly toxic carcinogen. May cause irritation on contact. Hazardous decomposition products.

Safety Profile

Confirmed carcinogen with experimental neoplastigenic data. Mildly toxic by ingestion. When heated to decomposition it emits very toxic fumes of Cl-, HCl, and phosgene. See also BENZENE HEXACHLORIDE and other benzenehexachloride entries.

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.

환경귀착

Soil. No biodegradation of β-BHC was observed under denitrifying and sulfate-reduc ing conditions in a contaminated soil collected from The Netherlands (Bachmann et al., 1988). In four successive 7-day incubation periods, β-BHC (5 and 10 mg/L) was recalci trant to degradation in a settled domestic wastewater inoculum (Tabak et al., 1981).
Chemical/Physical. Emits very toxic fumes of chlorides, hydrochloric acid and phos gene when heated to decomposition (Lewis, 1990). β-BHC will not hydrolyze to any reasonable extent (Kollig, 1993).

운송 방법

UN2761 Organochlorine pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

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.

폐기물 처리

A process has been developed for the destructive pyrolysis of benzene hexachloride @ 400 500℃ with a catalyst mixture which contains 5 10% of either cupric chloride, ferric chloride; zinc chloride; or aluminum chloride on activated carbon.
