АЛДРИН химические свойства, назначение, производство
Химические свойства
off-white solid
Физические свойства
Colorless to white, odorless crystals when pure; technical grades are tan to dark brown with a
mild, characteristic chemical odor. The odor threshold concentration in water is 17 μg/kg
(Sigworth, 1964).
Использование
Aldrin has been used as an insecticide for soil insects and the
control of termites around buildings. Industrial exposures
occur among groups that have been involved in the manufacture
of aldrin, and in the handling and spraying of suspensions
and emulsions of this compound.
Определение
ChEBI: An organochlorine compound resulting from the Diels-Alder reaction of hexachlorocyclopentadiene with norbornadiene. It was widely used as an insecticide before being banned in the 1970s as a persistent organic pollutant.
Общее описание
Aldrin, cast solid is a brown to white solid. If the large pieces are broken up or powdered, ALDRIN is toxic by inhalation and skin absorption. ALDRIN is insoluble in water and noncombustible. ALDRIN is used as an insecticide.
Реакции воздуха и воды
Insoluble in water.
Профиль реактивности
ALDRIN may be sensitive to prolonged exposure to light. ALDRIN is stable to heat and in the presence of inorganic and organic bases. ALDRIN is stable to hydrated metal chlorides and mild acids. ALDRIN is thermally stable up to 392° F and ALDRIN is stable between pH 4 and 8. ALDRIN reacts with concentrated acids and phenols in the presence of oxidizing agents. ALDRIN can be corrosive to metals. ALDRIN can react with acid catalysts, acid oxidizing agents and active metals.
Опасность
Toxic by skin absorption. Central nervous
system impairment, and liver and kidney damage.
Questionable carcinogen.
Угроза здоровью
Poisoning by aldrin usually involves convulsions due to its effects on the central nervous system. Reproductive effects and liver effects have also been reported. It is classified as an extremely toxic chemical. Probable oral lethal dose for humans is between 7 drops and one oz. for a 150 lb. adult human. Conflicting reports of carcinogenicity of ALDRIN remain an area of controversy. Similar chemically and toxicologically to dieldrin.
Пожароопасность
When heated to decomposition, ALDRIN emits toxic fumes of chlorine containing compounds. Commercial solutions may contain flammable or combustible liquids. The dry powder will not burn. Container may explode in heat of fire. Avoid concentrated mineral acids, acid catalysts, acid oxidizing agents, phenols, or active metals.
Профиль безопасности
Suspected carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by ingestion, skin contact, intravenous, and intraperitoneal routes. Human systemic effects by ingestion: excitement, tremors, and nausea or vomiting. An experimental teratogen. Other experimental reproductive effects. Continued acute exposure causes liver damage. Human mutation data reported. See also CHLORINATED HYDROCARBONS. When heated to decomposition it emits toxic fumes of Cl-.
Канцерогенность
Rodent carcinogenicity evaluations
of aldrin have been extensively reviewed, with
the conclusion that the mouse-specific hepatocarcinogenic
activity of aldrin occurs through a nongenotoxic mode of
action involving promotion of spontaneously initiated liver
cells.
