Density:2.03 g/cm3 @ Temp: 20 °C
Melting Point:172.5 °C
Boiling Point:407.5 °C
Water Solubility:Insoluble in cold water; decomposed by hot water, yielding H2S; Soluble in carbon disulfide (60% w/w at 20 deg C); soluble in benzene, similar hydrocarbons, phorphorus trichloride
Storage Conditions:Protect against physical damage. Store in cool, ventilated place. Separate from other materials.
Explosive limit:Flammable by spontaneous ignition.
Experimental Properties:Stable to air|Heat of fusion: -154 kJ/mol|Phosphorus sesquisulfide decomposes (hydrolyzes) in water with the hydrolysis reaction relatively slow in cold water but becoming faster upon heating producing mainly hydrogen sulfide and orthophosphoric acid, H3PO4; in neutral solutions, the hydrolysis products include PH3 (3%), H3PO2 (38%), H3PO3 (49%) and H3PO4 (6)(1); in alkaline solutions, the hydrolysis products include PH3 (5%), H3PO2 (15%), H3PO3 (75%)
Air and Water Reactions:Highly flammable.Slowly decomposed by water to form phosphoric acid and toxic hydrogen sulfide gas (H2S). May ignite on contact with water or moist air.
Reactive Group:Sulfides, Inorganic
Reactivity Alerts:Highly Flammable
Reactivity Profile:PHOSPHORUS SESQUISULFIDE is a reducing agent.
Autoignition Temperature:212 °F (100 °C)
