Sesquisulfides

Properties and Reactions. Phosphorus combines with sulfur to form the binary tetraphosphoms trisulfide [1314-85-8] (phosphoms sesquisulfide), P4S2, (1) tetraphosphoms pentasulfide [12137-70-1] ( )j tetraphosphoms heptasulfide [12037-82-0] P) and phosphoms(V)... [Pg.363]

Phosphoms(V) sulfide, an important commodity in the United States since about 1920, is the dominant commercial material. Phosphoms sesquisulfide, P4S2, has been made commercially since about 1900. Phosphoms heptasulfide was introduced as a small-scale commercial product in 1940. [Pg.364]

Uses. Phosphoms(V) sulfide is used in the manufacture of lubricating oil additives, insecticides, ore flotation agents, and specialty chemicals. Phosphoms sesquisulfide, P4S2, has been used extensively in the manufacture of stnkeanywhere matches (qv). In addition, small quantities are used in fireworks (see Pyrotechnics). [Pg.365]

Phosphorus sesquisulfide P4S3 [1314-85-8] M 220.1, m 172 . Extracted with CS2. filtered and evapd to dryness. Placed in H2O, and steam was passed through for an hour. The H2O was then removed, the solid was dried, followed by crystallisation from CS2 [Rogers and Gross J Am Chem Soc 74 5294 1952]. [Pg.451]

The spontaneous flaming of WP in air can also be made more reliable when a eutectic mixt of 55% WP with 45% phosphorus sesquisulfide (P4S3) is formed. This material (mp 40°, d 1.84g/cc) was used in WWII in one-shot flame throwers designed to protect tanks against suicide attacks by infantry (El Antipersonnel Tank Protector) (Ref 4, p 27)... [Pg.731]

Tetraphosphorus trisulfide (P4S3) which is also called phosphorus sesquisulfide, can be obtained by heating a stoichiometric mixture of phosphorus and sulfur at 180 °C in an inert atmosphere. The compound (m.p. 174 °C) is soluble in toluene, carbon disulfide, and benzene, and it is used with potassium chlorate, sulfur, and lead dioxide in matches. [Pg.503]
