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.
Reactivity Profile
THIOPHOSGENE(463-71-8) 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.
Air & Water Reactions
Reacts with water to evolve hydrogen chloride, carbon disulfide, and carbon dioxide. Reaction is slow unless the water is hot.
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.
Potential Exposure
Primary irritant (w/o allergic reaction). There is not large-scale production of the chemical in the United States It is used to make other chemicals and in laboratory synthesis.
First aid
Get medical attention at once after any exposure to this compound. Inhalation: remove victim from exposure. Administer oxygen as soon as possible; support respiration; watch for pulmonary edema. Eyes: irrigate with large quantities of water for 15 minutes. Skin: flush with water. Ingestion: Do NOT induce vomiting; give large amount of water.
Shipping
UN2474 Thiophosgene, Hazard class: 6.1; Labels: 6.1-Poison Inhalation Hazard; Inhalation Hazard Zone B. PG 2. STN: 49 232 98.
Incompatibilities
Vapors may form explosive mixture with air. Incompatible with water and alcohols. Reacts with water releasing toxic hydrogen chloride, carbon disulfide, and carbon dioxide. Reaction is slow unless the water is hot. Decomposes above 200℃ to highly flammable carbon bisulfide and carbon tetrachloride. Corrodes metals, rubber and some plastics in the presence of moisture. 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
