登记用途：Uses: Used to make herbicides、drugs、dyes、and plastics、Also used as an electrolyte in lithium batteries、[ACGIH]、Battery Manufacturing [Category: Industry]、Toxic Gas from Spilling Chemical in Water [Category: Other]、For making acyl chlorides、to replace、hydroxide or sulfhydryl、groups with chlorine atoms、reacts with Grignard reagents to form the corresponding sulfoxides.、... Used to make acyl chlorides and to synthesize pharmaceuticals including drugs and vitamins. It is used to make dyes、to prepare organic chlorine compounds、as a solvent in the production of herbicides、and as an electrolyte in lithium batteries. Thionyl chloride is also used to prepare polyarylate-type engineering thermoplastics made from iso- and tere-phthaloyl chlorides.、Manufacture of、pesticides、engineering plastics、chlorinating agent、catalyst、Required in the manufacture of methylphosphonic dichloride、a key precursor for the nerve gas Sarin.、In the synthesis of various nerve agents、Methods of Manufacturing: Thionyl chloride is now generally produced by treating SO2 or SO3 with SCl2 at ca. 150-250 °C in the presence of activated carbon. The crude product is purified by distillation after addition of sulfur. Crude thionyl chloride production is a continuous process、but the distillation is carried out either continuously or in batches. The side product SO2 can be reacted with chlorine to give SO2Cl2 and thus recycled. ... Technical-grade thionyl chloride can contain sulfur chlorides、SO2、and SO2Cl2. Sulfur chlorides can be removed by distillation over sulfur、in some cases with the addition of FeCl3 or AlCl3. For laboratory-scale purification、distillation with triphenyl phosphite or dipentene is recommended. Modern processes give thionyl chloride in a quality which does not require any additional purification.、Prepared by the oxidation of sulfur dichloride with sulfur trioxide ... .、Edwards、United States patent 2362057 (1944 to Hooker Electrochemical) ... .、Impurities: The following impurities can be present: <、= 0.3% SO2、<、= 0.2% SO2Cl2、= 0.05% sulfur chlorides、and <、= 0.1% evaporation residue.、Formulations、Preparations: Technical-grade ... The thionyl chloride content should be min. 99.6%.、Grade: 93%、97.5%、U.S. Production: (1972) GREATER THAN 4.54X10+5 GRAMS、(1975) GREATER THAN 4.54X10+5 GRAMS、Production volumes for non-confidential chemicals reported under the Inventory Update Rule.
