Belongs to the Following Reactive Group(s). Two are of commercial significance, phosphorus pentasulfide (P 4 S 10), which is made on a kiloton scale for the production of other organosulfur compounds, and phosphorus sesquisulfide (P 4 S 3), used in the production of "strike … Video shows what tetraphosphorus trisulfide means. P4Se3 and P4S3 adopt the same structures. Forms sulfur dioxide and phosphorus pentaoxide during combustion. The compound was discovered by G. Lemoine and first produced safely in commercial quantities in 1898 by Albright and Wilson. Reacts with water to form phosphoric acid, a corrosive material. In appearance, properties and structure it is similar to graphite , being black and flaky, a conductor of electricity, and having puckered sheets of linked atoms. Phosphorus pentasulfide is manufactured for the production of other organosulfur compounds, and Phosphorus sesquisulfide is used in the production of matches. The trihalides of phosphorus have been thoroughly studied. Some matches, called strike-anywhere matches, may be ignited by striking them on any rough surface. CAS Number. Under higher temperatures, mixed chalcogenide molecules P4S2Se and P4SSe2 will form. In the list of chemical elements, it is designated the symbol P, while its atomic number is 15. It is a derivative of the tetrahedral (P4) unit from insertion of sulfur into three P-P bonds. In appearance, properties and structure it is similar to graphite , being black and flaky, a conductor of electricity, and having puckered sheets of linked atoms. Forms sulfur dioxide and phosphorus pentaoxide during combustion. Depending on purity, samples can appear yellow-green to grey. Several sulfides of arsenic, antimony, and bismuth are known. Phosphorus sesquisulfide definition, (not in scientific use) a yellow, crystalline, flammable substance, P4S3, insoluble in cold water and decomposed by hot water: used chiefly in organic synthesis and in the manufacture of matches. Average rating 3.7 / 5. It is a derivative of the tetrahedral (P4) unit from insertion of sulfur into three P-P bonds. White phosphorus is widely used to make organophosphorus compounds through intermediate phosphorus chlorides and two phosphorus sulfides, phosphorus pentasulfide and phosphorus sesquisulfide. Phosphorus sesquisulfide is the inorganic compound with the formula P4S3. This yellow solid is one of two commercially produced phosphorus sulfides. [5], P4S3 and potassium chlorate, together with other materials, comprises the heads of "strike-anywhere matches". The use of white phosphorus itself is limited to ingredients in metallurgy and rodent poisons. The P-S and P-P distances are 2.090 and 2.235 Å, respectively. The Germans developed the first man-portable flamethrowers and flame warfare tactics, and other nations soon followed suit. Heating P 4 O 6 with sulfur produces an oxysulfide having the formula P 4 O 6 S 4 that has a structure similar to that of P 4 O 10, except the terminal (nonbridging) oxygen atoms are replaced by sulfur atoms. The use of white phosphorus itself is limited to ingredients in metallurgy and rodent poisons. PHOSPHORUS SESQUISULFIDE is a reducing agent. A few other mixed sulfur-oxygen compounds of phosphorus are known. No votes so far! Click on a star to rate it! It is obtained by heating white phosphorus under high pressures (12,000 atmospheres). [citation needed], Exposure to "strike anywhere" matches containing phosphorus sesquisulfide can cause contact dermatitis, usually in the pocket area but also on the face. Chemsrc provides phosphorus sesquisulfide(CAS#:1314-85-8) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Common Name. Phosphorus sesquisulfide is the inorganic compound with the formula P 4 S 3.It was developed by Henri Sevene and Emile David Cahen in 1898 as part of their invention of friction matches that did not pose the health hazards of white phosphorus [2].This yellow solid is one of two commercially produced phosphorus sulfides.It is a component of "strike anywhere" matches. The Tetraphosphorus trisulfide molecule contains a total of 9 bond(s) There are 9 non-H bond(s), 9 multiple bond(s), 9 aromatic bond(s), 1 three-membered ring(s), 3 five-membered ring(s) and 3 six-membered ring(s). This article contains public domain text from the NOAA as cited. Several molecular phosphorus sulfides are known in addition to P 4 S 3: three isomers of P 4 S 4, two isomers of P 4 S 5, P 4 S 6, P 4 S 7, P 4 S 8, P 4 S 9, and P 4 S 10. It is obtained by heating white phosphorus under high pressures (12,000 atmospheres). Web site owner: National Oceanic and Atmospheric Administration. including trade names and synonyms. It is a component of "strike anywhere" matches. 2.03. one of the most common allotropes of phosphorus and is considered to be a derivative of the P4 molecule No votes so far! [2][1] This yellow solid is one of two commercially produced phosphorus sulfides. Also, unlike safety matches, these matches don’t need any specific striking surface; the phosphorus sesquisulfide that is present packs enough of a punch to ignite even with the help of a little friction.
