Use of thionyl chloride
Sulfoxide chloride is an important organic chemical intermediate.
Since sulfoxide chloride can interact with water, it can react with hydrated salts of metal chlorides to produce anhydrous metal chlorides. MCln · xH2O x SOCl2 → MCln x SO2 2x HCl sulfoxide chloride and transition metal oxide are heated and refluxed to obtain the metal's chlorine oxide: WO3 2SOCl2 → WOCl4 2SO2 sulfoxide chloride is widely used to convert carboxylic acid and alcohol into. and other Compared with reagents, thionyl chloride is often the preferred reagent, because its reaction products, sulfur dioxide and sulfur dioxide, are gaseous and easy to separate. Excess sulfoxide chloride can be removed by distillation. RC(=O)-OH O=SCl2 →RC(=O)-Cl SO2 HCl R-OH O=SCl2 → R-Cl SO2 HCl
The thionyl chloride can be reacted with the monosubstitution to form corresponding. Amides can react with thionyl chloride to form iminoyl chloride. Amides will continue to be dehydrated when co heated with thionyl chloride.
