Химические свойства
Sulfotep is a yellow mobile liquid. Garliclike odor.
Использование
Sulfotep is used to control aphids, thrips, mites and whiteflies in
glasshouses by fumigation. It also used to control sciarid and phorid flies
in mushrooms.
Общее описание
Tetraethyl dithiopyrophosphate and compressed gas mixture is a liquid charged with a gas. Tetraethyl dithiopyrophosphate is a yellow liquid. Its vapor is heavier than air. SULFOTEP is lethal by skin absorption and inhalation. Prolonged exposure of the containers to fire or heat may result in their violent rupturing and rocketing.
Профиль реактивности
Organothiophosphates, such as TETRAETHYL DITHIOPYROPHOSPHATE, 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. SULFOTEP is incompatible with the following: Strong oxidizers, iron [Note: Corrosive to iron.] .
Опасность
Toxic by ingestion, inhalation, and skin
absorption; cholinesterase inhibitor; use may be
restricted. Questionable carcinogen.
Профиль безопасности
Poison by ingestion, skin contact, inhalation, intramuscular, intraperitoneal, subcutaneous, and intravenous routes. A cholinesterase inhbitor type of insecticide. When heated to decomposition it emits toxic fumes of POx and SOx. See also PARATHION.
Возможный контакт
Sulfotep is used in greenhouse fumigant formulations for control of aphids, spider mites; thrips, whiteflies, etc.
Экологическая судьба
Soil. Cleavage of the molecule yields diethyl phosphate, monoethyl phosphate and
phosphoric acid (Hartley and Kidd, 1987).
Chemical/Physical. Emits toxic oxides of sulfur and phosphorus oxides when heated
to decomposition (Lewis, 1990).
Метаболический путь
Sulfotep and related compounds may be formed photochemically from
a number of phosphorodithioate and phosphorothioate insecticides
including azinphos-methyl, chlorpyrifos, malathion, methidathion and
phosalone (Abdelbagi and Gaston, 1998). Since sulfotep has a rather
high mammalian toxicity, this may be of some toxicological sigruficance.
Sulfotep is transformed in the environment via oxidative desulfuration
to the highly active anti-cholinesterase compounds monosulfotep and
tetraethyl pyrophosphate. It is deactivated by hydrolysis to O,O-diethyl
phosphorothioate and diethyl phosphate.
Перевозки
UN1704 (Sulfotep) Tetraethyl dithiopyrophosphate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
Несовместимости
Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine,bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Hydrolyzes very slowly in aqueous solution. Attacks some forms of plastic, rubber and coating. Corrosive to iron.
Утилизация отходов
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with 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. Incineration with added flammable solvent in furnace equipped with afterburner and alkaline scrubber.
