Phosphorus pentasulfide Chemical Properties,Usage,Production

Chemical Properties
Yellow to greenish powder
General Description
A greenish yellow solid with an odor of rotten eggs that may paralyze the sense of smell at hazardous concentrations in air. Density 2.04 g / cm3. Phosphorus pentasulfide is used for making lube oil additives, insecticides, flotation agents, safety matches, blown asphalt, and other products and chemicals.
Air & Water Reactions
Highly flammable. May heat and spontaneously ignite in presence of moisture [Haz. Chem. Data. 1969]. Reaction with water forms toxic hydrogen sulfide gas and phosphoric acid. Dangerous when wet.
Reactivity Profile
PHOSPHORUS PENTASULFIDE reacts vigorously with strong oxidants. Exothermically violent decomposition reaction with water, steam or acids to produce irritating fumes of phosphorus pentaoxide and highly toxic hydrogen sulfide gas. May ignite in contact with limited amounts of water [Haz. Chem. Data, 1975, p. 239]. Can be ignited by sparks or friction and its dust presents an explosion hazard in air at sufficient concentrations. Hydrogen sulfide gas evolved from reactions with water may also form explosive mixtures with air.
Health Hazard
Hydrogen sulfide gas formed by reaction with moisture can cause death by respiratory failure. The gas also irritates eyes and respiratory system. The solid irritates skin and eyes; the symptoms may be delayed several hours.
Fire Hazard
Special Hazards of Combustion Products: Products of combustion include sulfur dioxide and phosphorus pentoxide, which are irritating, toxic and corrosive.
