Dimethyl chlorothiophosphate Chemical Properties,Uses,Production

Chemical Properties

clear colorless to light yellow liquid

Uses

Dimethyl chlorothiophosphate is used as an intermediate in the manufacture of insecticides, pesticides, fungicides, oil and gasoline additives, plasticizers, corrosion inhibitors, flame-retardants, and flotation agents.

Preparation

Dimethyl chlorothiophosphate is prepared by reaction of phosphorus pentasulfide & methyl alcohol followed by reaction of the resulting dimethyl phosphorodithioate with chlorine.

General Description

Dimethyl chlorothiophosphate is a colorless to light amber liquid. Used as a chemical intermediate for insecticides, pesticides, and fungicides; oil and gasoline additives; plasticizers; corrosion inhibitors; flame retardants; and flotation agents. Not registered as a pesticide in the U.S. (EPA, 1998)

Reactivity Profile

Organothiophosphates, such as Dimethyl chlorothiophosphate, 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

Dimethyl chlorothiophosphate is a strong irritant to the eyes, skin, and mucous membranes.

Fire Hazard

Dimethyl chlorothiophosphate may burn but does not ignite readily. Dimethyl chlorothiophosphate may ignite combustibles (wood, paper, oil, etc.). When heated Dimethyl chlorothiophosphate emits very toxic fumes of chlorine containing compounds, phosphorus oxides, and sulfur oxides.

Safety Profile

Poison by inhalation. Moderately toxic by ingestion and skin contact. Corrosive. When heated to decomposition it emits very toxic fumes of Cl-, POx, and SOx
