Sulfoxide chloride is an inorganic compound with the chemical formula SoCl60. It is a colorless or yellow odorous liquid with a strong pungent odor. It is miscible in organic solvents such as benzene, chloroform, carbon tetrachloride, etc. In case of water hydrolysis, decomposition by heating. It is mainly used in the manufacture of acyl chloride, but also in the production of pesticides, pharmaceuticals, dyes, etc. Chinese name: sulfoxide chloride foreign name: thionyl chloride alias: sulfite chloride chemical formula: SoCl2 molecular weight: 118.97CAS registration number: 7719-09-7EINECS registration number: 231-748-8 melting point: -105 ℃ boiling point: 78.8 ℃ density: 1.638 g/cm06 appearance: light yellow to red liquid Safety description: S26; S27; S28; S36/37/39; S45 is mainly used as chlorinating agent for synthesis or replacement of organic matter, such as alcohol hydroxyl, acid anhydride, organic sulfonic acid and nitro compound, chloroacylating agent synthesized by thiazoline, pyrrolidine, amide, etc., in closed-loop reaction, and also used to prepare catalyst for the synthesis of pharmaceutical intermediates, organic anhydride, dye intermediates, etc.. It is also used as an analytical reagent for the determination of aromatic amines and aliphatic amines. It can be prepared by co-heating calcium sulfite and phosphorus pentachloride. Used as a chlorinating agent for organic synthesis, such as the chlorination of alcohol hydroxyl groups, the chlorination of carboxylic acids, the chlorination of anhydrides, the chlorination of organic sulfonic acids or nitro compounds. Manufactures acyl chloride. Manufacture of pharmaceutical intermediates, such as deworming net, odorless synthromycin. It is also used as a dehydrator and solvent. Content: 99.90% Specification: 300kg/barrel can be used as a raw material for manufacturing batteries. Storage Precautions: Store in a cool, ventilated warehouse. The storage temperature should not exceed 25℃ and the relative humidity should not exceed 75%. Keep container sealed. It should be stored separately from alkalis, etc., and should not be mixed. The storage area should be equipped with spill emergency treatment equipment and suitable storage materials.
