CHLORMEPHOS химические свойства, назначение, производство
Использование
Chlormephos is used to control soil insects such as wireworms in a
number of crops.
Общее описание
Colorless liquid. Used as a soil insecticide. Not registered as a pesticide in the U.S.
Реакции воздуха и воды
Slightly soluble in water [Farm Chemicals Handbook].
Профиль реактивности
Organophosphates, such as CHLORMEPHOS, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Угроза здоровью
(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) CHLORMEPHOS is poisonous; it may be fatal if inhaled, swallowed, or absorbed through the skin.
Пожароопасность
(Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Container may explode in heat of fire. Fire and runoff from control water may produce irritating or poisonous gases.
Метаболический путь
Chlormephos is a soil insecticide with considerable vapour phase activity.
The main soil metabolite is ethion. The mechanism of hydrolysis of
chlormephos is mainly by the nucleophilic attack of OH- on the Smethylene
carbon to yield O,O-diethyl phosphorodithioate and in this
respect it is similar to mecarbam. This mechanism may afford ethion
when the nucleophile is O,O-diethyl phosphorodithioate. The other
mechanism of hydrolysis is by attack on phosphorus to yield O,O-diethyl
phosphorothioate and these two routes of hydrolytic degradation
apparently dominate the metabolism of the insecticide.
Метаболизм
In soils, chlormephos is converted to
ethion by reaction with the hydrolytic product, O,O-diethyl
hydrogen phosphorothioate.
