|Section2= |Section7= }} Thiophosphoryl chloride is an inorganic compound with the formula PSCl3.〔Spilling, C. D. "Thiophosphoryl Chloride" in Encyclopedia of Reagents for Organic Synthesis John Wiley & Sons, Weinheim, 2001. . Article Online Posting Date: April 15, 2001.〕 It is a colorless liquid with a pungent odor that fumes in moist air. It is synthesized from phosphorus chloride and used to thiophosphorylate organic compounds, such as to produce insecticides. ==Synthesis== Thiophosphoryl chloride can be generated by several reactions starting from phosphorus trichloride. The most common and practical synthesis, hence used in industrial manufacturing, is directly reacting phosphorus trichloride with excess sulfur at 180 °C.〔Betterman, G.; Krause, W.; Riess, G.; Hofmann, T. “Phosphorus Compounds, Inorganic” Ullmann’s Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. .〕 :PCl3 + S → PSCl3 Using this method, yields can be very high after purification by distillation. Catalysts facilitate the reaction at lower temperatures, but are not usually necessary. Alternatively, it is obtained by combining phosphorus pentasulfide and phosphorus pentachloride.〔Martin, D. R.; Duvall, W. M. “Phosphorus(V) Sulfochloride” Inorganic Syntheses, 1953, Volume IV, p73. .〕 :3 PCl5 + P2S5 → 5 PSCl3 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thiophosphoryl chloride」の詳細全文を読む スポンサード リンク
