Stability: Thiophosgene (463-71-8) is stable. but reacts violently with water to produce toxic fumes. Incompatible with water, alcohols. Refrigerate at 2-8°C

Thiophosgene (463-71-8) is  intermediates in the preparation of sulfur acaricide Diafenthiuron, but also an important intermediate in the preparation of thio carbamate insecticides and herbicides.

Phosgene sulfu is obtained by the reduction of Chloride methyl mercaptan.  add  potassium iodide into a mixture of  entire chlorine methyl mercaptan, tetrachloroethane and water with stirring; add sulfur dioxide at room temperatur,with  temperature automatically rising in the reaction , adjust ventilation to maintain the temperature at 50 ~ 70 °C. When temperature of reaction solution is not rising and sulfur dioxide absorption is no longer apparent, stop ventiling, put it aside until it is cool, take the sub-fractionation o organic layer , collect sulfur phosgene distillated below76 °C.

Chemical Properties: Thiophosgene (463-71-8) is reddish liquid .
General Description: A reddish liquid. Boiling point 73.5°C. A severe eye irritant. May severely burn skin on contact. Very toxic by inhalation and by skin absorption.
Air & Water Reactions: Reacts with water to evolve hydrogen chloride, carbon disulfide, and carbon dioxide. Reaction is slow unless the water is hot.
Reactivity Profile: Thiophosgene is incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Liberates hydrogen sulfide upon reaction with acids.
Health Hazard: Inhalation causes irritation of respiratory system and delayed pulmonary edema. Vapor irritates eyes. Liquid burns skin and eyes. Ingestion causes irritation of mouth and stomach.
