General Description
A grayish yellow solid.
Air & Water Reactions
Highly flammable. May spontaneously ignite in moist air or in contact with water. Produce acidic and corrosive phosphorus pentaoxide and sulfur dioxide when burned. Produces phosphoric acid and hydrogen sulfide, a toxic flammable gas with water.
Reactivity Profile
PHOSPHORUS TRISULFIDE is a reducing agent. Reacts vigorously with oxidizing agents, including inorganic oxoacids, organic peroxides and epoxides.
Health Hazard
Highly toxic: contact with water produces toxic gas, may be fatal if inhaled. Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.
Fire Hazard
Produce flammable and toxic gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Containers may explode when heated. Runoff may create fire or explosion hazard.
