[Application]: Thionyl chloride is an important intermediate of organic chemistry and is mainly used in medicine, pesticides, dyes and industrial organic synthesis industry as chlorinating agent. Consumption structure: the pharmaceutical industry accounted for 25%, pesticide industry accounted for 50%, dyestuff industry accounted for 5% and other industries accounted for 20%. The pesticide industry contributes the major part for consumption of thionyl chloride and is mainly used for the production of inabenfide, valerate, fenvalerate, mosquito-killing dimerthrin, flucythrinate, diflubenzuron, isocarbophos, fenpropathrin, endosulfan, deltamethrin, a (b) group chlorpyrifos, oxazolidinone, quizalofop and warfarin.
Because thionyl chloride can have fierce reaction with water, it is able to have reaction with metal chloride hydrated salt for production with anhydrous metal chlorides. MCln • xH2O + x SOCl2 → MCln + x SO2 + 2x HCl
Thionyl chloride was subjected heating reflux with a transition metal oxide and can further generate the corresponding oxychloride of the metal: WO3 + 2SOCl2 → WOCl4 + 2SO2
Thionyl chloride has been widely used for converting alcohol and the carboxylic acid into the corresponding acid chloride and chlorinated hydrocarbons. Compared with other agents (such as phosphorus penta-chloride), thionyl chloride is often the preferred reagents, because both the reaction product of sulfur dioxide and hydrogen chloride are gaseous and is easily to be separated. The excess amount of thionyl chloride can be removed by distillation. RC (= O)-OH + O = SCl2 → RC (= O)-Cl + SO2 + HCl R-OH + O = SCl2 → R-Cl + SO2 + HCl. Sulfoacid can react with thionyl chloride to generate sulfonyl chloride. Sulfinic acid can have reaction with thionyl chloride to generate sulfinyl chloride. Phosphonic acid can have reaction with thionyl chloride to generate phosphine chloride.
Thionyl chloride can react with mono-substituted formamide to generate the corresponding isonitriles. Amide can react with thionyl chloride to generate imine acyl chloride. Primary amide, upon co-heating with thionyl chloride, will be further dehydrated to become nitrile.
[Storage and transporation]:
Store in a cool , ventilated warehouse. Keep away from fire and heat sources. The packaging is required to be hermetic and not in contact with air. It should be stored separately from oxidants, acids, alkalis, etc.
