클로로벤질산 C화학적 특성, 용도, 생산
개요
Chlorobenzilate is an organochlorine pesticide belonging to
the same class as dichlorodiphenyltrichloroethane (DDT).
It was originally developed by Ciba–Geigy and introduced
in 1952.
화학적 성질
Ethyl 4,40
-dichlorobenzilate is a yellow solid
when pure. The technical product is a brownish liquid.
용도
The primary use of chlorobenzilate is as an acaricide for mite
control on citrus crops and in beehives. It has a narrow
insecticidal action, killing only mites and ticks. Historically,
chlorobenzilate was used as a synergist for DDT. Although
now banned for use in the United States and Europe, it is
believed to be used on crops other than citrus in other
countries.
일반 설명
Viscous yellow liquid or pale yellow crystals. Light brown crystalline solid.
공기와 물의 반응
Insoluble in water.
반응 프로필
CHLOROBENZILATE is hydrolyzed by alkalis and strong acids. Incompatible with lime .
건강위험
Moderately toxic by oral route; toxic symptoms similar to DDT and Perthane; ingestionof large dose can produce nausea, vomiting,tremor and convulsions; skin or eye contactcan cause irritation; application of 25 mgproduced moderate irritation of eye inrabbits; adequate evidence of carcinogenicityin experimental animals; produced tumors inrats and mice; evidence of carcinogenicity inhumans remains unknown.
LD50 oral (rat): 700 mg/kg
LD50 oral (mouse): 729 mg/kg.
화재위험
Flash point data for CHLOROBENZILATE are not available; however, CHLOROBENZILATE is probably combustible.
Safety Profile
Suspected carcinogen
with experimental carcinogenic,
neoplastigenic, and tumorigenic data.
Moderately toxic by ingestion. A skin and
eye irritant. A pesticide. When heated to
decomposition it emits toxic fumes of Cl-.
잠재적 노출
It is a buffer in many chemical intermediates; an organochlorine miticide; to kill mites, ticks,
and other insects; as a synergist for DDT.
Incompatibilities: Strong acids, strong bases; lime.
환경귀착
Biological. Rhodotorula gracilis, a yeast isolated from an insecticide-treated soil,
degraded chlorobenzilate in a basal medium supplemented by sucrose. Metabolites identified by this decarboxylation process were 4,4′-dichlorobenzilic acid, 4,4′-dichlorobenzophenone and carbon dioxide (Miyazaki et al., 1969, 1970).
Soil. Though no products were identified, the half-life of chlorobenzilate in two fine
sandy soils was estimated to be 1.5–5 weeks (Wheeler, 1973).
Photolytic. Chlorobenzilate should not undergo direct photolysis since it does not
absorb UV light at wavelengths greater than 290 nm (Gore et al., 1971).

폐기물 처리
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform to EPA regulations governing
storage, transportation, treatment, and waste disposal. In
accordance with 40CFR165, follow recommendations for
the disposal of pesticides and pesticide containers. Must be
disposed properly by following package label directions or
by contacting your local or federal environmental control
agency, or by contacting your regional EPA office.
