DIOXATHION Chemical Properties,Uses,Production
Chemical Properties
dark amber viscous liquid
Uses
Dioxathion is an organophosphate pesticide. It is used as an insecticide on livestock and acaricide on citrus fruits.
General Description
Tan liquid (technical grade is brown). Used for the control of insects and mites on grapes, citrus, walnuts, ornamentals, apples, pears, and quince. Also used as a spray or dip for the control of ticks, lice, hornfly, and sheep ked on cattle, goats, sheep, and hogs.
Air & Water Reactions
Insoluble in water. DIOXATHION is stable in water at a neutral pH.
Reactivity Profile
DIOXATHION is heat sensitive. DIOXATHION may react with iron or tin surfaces. DIOXATHION may be hydrolyzed by strong acids or alkalis. . Organophosphates 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.
Health Hazard
Very toxic. Probable oral lethal dose for humans is 50-500 mg/kg or between 1 teaspoonful and 1 oz. for a 70 kg (150 lb.) person. It is a cholinesterase inhibitor. Death is primarily due to respiratory arrest arising from failure of the respiratory center, paralysis of respiratory muscles, intense bronchoconstriction, or all three.
Fire Hazard
Shock can shatter container, releasing contents. (Non-Specific -- Organophosphorus Pesticide, Liquid, n.o.s.) Container may explode in heat of fire. Fire may produce irritating or poisonous gases. Runoff from fire control water may give off poisonous gases. Runoff from fire control or dilution water may cause pollution. When heated to decomposition, DIOXATHION emits highly toxic fumes of oxides of nitrogen, phosphorus, and sulfur. Avoid alkali materials and heat. DIOXATHION is unstable to iron or tin surfaces and when mixed with certain carriers.
Safety Profile
Poison by ingestion, inhalation, skin contact, and intraperitoneal routes. Mutation data reported. A cholinesterase inhibitor. When heated to decomposition it emits very toxic fumes of POx, and SOx,. See also PARATHION
