Thionyl Chloride
Pale yellow to red, smoky liquid, with strong irritating odor. It is soluble in benzene, chloroform, carbon tetrachloride and other organic solvents. When it is hydrolyzed by water, it is decomposed by heating. It is mainly used in the manufacture of acyl chlorides, and also in the production of pesticides, medicines, dyes and so on.
Molecular formula: SOCl ramming
Category of chemicals: inorganic substances - sulfides
Storage: sealed storage
Appearance: Light yellow to red liquid
Main uses
Chlorides for the synthesis or substitution of organic compounds, such as alcohols, hydroxyl groups, anhydrides, organic sulfonic acids and nitro compounds, chloroacylators for the synthesis of thiazoline, pyrrolidine and amides in closed-loop reactions, and catalysts for the synthesis of pharmaceutical intermediates, organic anhydrides, dye intermediates, etc. In addition, it is also used as an analytical reagent for the determination of aromatic amines and aliphatic amines. [4] It can be prepared by co-heating calcium sulfite with phosphorus pentachloride.
Used as chlorinating agent for organic synthesis, such as chlorination of alcohol hydroxyl group, chlorination of carboxylic acid, chlorination of anhydride, chlorine replacement of organic sulfonic acid or nitro compound. Manufacture of acyl chlorides. Manufacture of pharmaceutical intermediates, such as Tetramethrin and Oxytetracycline. It is also used as dehydrant and solvent.
Raw materials used to make batteries.
