Thionyl chloride best price cas 7719-09-7
Thionyl chloride also known as sulfinyl chloride, sulfur oxychloride, sulfur oxychloride,
dichlorosulfoxide, room temperature and pressure for colorless or light yellow liquid, pungent odor.
Relative density 1.676, 104.5 ℃ melting point, boiling point 78.8 ℃.
It is easily decomposed into sulfur dioxide and hydrogen chloride when exposed to water.
Soluble in benzene, chloroform and carbon tetrachloride.
Heated to 150 ° C to decompose, 150 ° C is decomposed completely.
Sulfoxide chloride is sometimes confused with sulfuric chloride (SO2Cl2),
but their chemical properties are quite different.
Its chlorine atom replaces the hydroxyl or the sulfide group ability to be remarkable.
Sulfoxide chloride can react with hydroxyl phenol or alcohol to form corresponding chloride.
Reaction with grignard reagent to form sulfoxide compounds.

1. Sulfoxide chloride can interact strongly with water,
so it can react with metal chloride to hydrate salt to make anhydrous metal chloride.
MCln·xH2O + x SOCl2 MCln + x SO2 + 2x HCl
2. Sulfoxide chloride and transition metal oxide are heated by reflux to
obtain the metal's chlorine oxides: WO3 + 2SOCl2 WOCl4 + 2SO2.
3. Sulfoxide chloride is widely used to convert carboxylic acids and
alcohols into corresponding acyl chloride and chlorinated hydrocarbons.
Compared with other reagents (such as phosphorus pentachloride),
sulfoxide chloride is often the preferred reagent because its reaction products
sulfur dioxide and hydrogen chloride are gaseous and easy to separate.
Excess sulfoxide chloride can be removed by distillation.

sulfonic acid reacts with sulfoxil chloride to form sulfonyl chloride.
Sulfonic acid reacts with sulfonic chloride to form sulfonic chloride.
Phosphonic acid reacts with sulfoxide chloride to form phosphonyl chloride.
4. Sulfoxide chloride can react with monosubstituted formamide to form corresponding isonitrile.
Amides can react with sulfoxides chloride to form imide chloride,
and the primary amides will continue to be dehydrated into nitriles when heated with sulfoxides chloride.
