A poison by ingestion.
A severe eye and skin irritant. Readily
liberates toxic hydrogen sulfide and
phosphorus pentoxide and evolves heat on
contact with moisture. Dangerous fire
hazard in the form of dust when exposed to
heat or flame. Spontaneous heating in the
presence of moisture. Moderate explosion
hazard in solid form by spontaneous
chemical reaction. Reacts with water, steam,
or acids to produce toxic and flammable
vapors; can react vigorously with oxidizing
materials. Incompatible with air, alcohols,
water. To fight fire, use CO2snow, dry
chemical, or sand. Used as an intermedate
in manufacturing lubricant addltives,
insecticides, and fertilizer agents. When
heated to decomposition it emits highly
toxic fumes of SO, and PO,. See also

| Hazard Information | Back Directory | [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, FREE FROM YELLOW AND WHITE PHOSPHORUS(1314-80-3) is used for making lube oil additives, insecticides, flotation agents, safety matches, blown asphalt, and other products and chemicals. | [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. | [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. | [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. | [Potential Exposure]
Phosphorus pentasulfide is used as an intermediate in the manufacture of lubricant additives; insecticides, flotation agents; lubricating oil; ignition compounds; and matches. It is also used to introduce sulfur into rubber, and organic chemicals, such as pharmaceuticals. | [Fire Hazard]
Special Hazards of Combustion Products: Products of combustion include sulfur dioxide and phosphorus pentoxide, which are irritating, toxic and corrosive. | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 2448 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. | [Shipping]
UN1340 Phosphorus pentasulfate, free from yellow or white phosphorus, Hazard Class: 4.3; Labels: 4.3-Dangerous when wet material, 4.1-flammable solid. | [Incompatibilities]
Flammable solid; dust may form explosive mixture with air. Contact with water forms phosphorus pentoxide and an explosive mixture of hydrogen sulfide with air. Phosphorus pentasulfide is incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, ammonia, strong acids, strong bases, alcohols. Reaction with water or moisture in the air releases heat, hydrogen sulfide (H2S), sulfur dioxide, and phosphoric acid. Pyrophoric hazard, may self-ignite in moist air. | [Description]
Phosphorus pentasulfide, is a nonmetallic inorganic compound . It is a yellow to greenish-yellow crystalline mass with an odor similar to hydrogen sulfide. It is a dangerous fire risk and ignites by friction or in contact with water. Boiling point is 995°F (535°C) and ignition temperature is 287°F (141°C). It decomposes upon contact with water or moist air, liberating toxic and flammable hydrogen-sulfide gas. Specific gravity is 2.09, so it is heavier than water. It is toxic by inhalation, with a TLV of 1 mg/m3 of air. The four-digit UN identification number is 1340. The NFPA 704 designation is health 2, flammability 1, and reactivity 2. Primary uses are in insecticides, safety matches, ignition compounds, and sulfonation. | [Chemical Properties]
Phosphorus pentasulfide is a greenish-gray to yellow, crystalline solid with an odor of rotten eggs. The Odor Threshold is 0.005 ppm.
| [Waste Disposal]
Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Decompose with water, forming phosphoric acid, sulfuric acid and hydrogen sulfide. Provisions must be made for scrubbing hydrogen sulfide emissions. The acids may then be neutralized and diluted slowly to solution of soda ash and slaked lime with stirring, then flush to sewer with large volumes of water. | [Uses]
In manufacture of lube oil additives and pesticides. manufacture of safety matches, ignition Compounds, and for introducing sulfur into organic Compounds. | [Uses]
Phosphorus pentasulfide (phosphoric sulfide, P2S5) is an insecticide. It is also an additive to
oils and a component of safety matches. | [Uses]
Phosphorus pentasulfide is used in the manufacture of lubricant additives, pesticides, safety matches, and flotation agents. | [Flammability and Explosibility]
Highlyflammable | [Purification Methods]
Purify P2S5 by extraction and crystallisation with CS2, using a Soxhlet extractor, and is heated in a CO2 atmosphere at 150o to remove solvent. It liberates H2S in moist air. HARMFUL VAPOURS. [Klements in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 568 1963.] |
