Chinese Name:苯磺酰氯  Alias: benzene sulfonyl chloride

English Name: Benzenesulfonyl chloride

CAS No.: 98-09-9 Molecular weight: 176.62

Molecular formula: c6h5clo2s; C6H5SOOCl

Appearance and properties: colorless transparent oily liquid

Steam pressure: 1.33kpa/120 ℃ Flash point: > 110 ℃

Melting point: 14.5 ℃ Boiling point: 251 ℃ / decomposition

Density: relative density (water = 1) 1.38

Solubility: easily soluble in ethanol and benzene, basically insoluble in water. When mixed with water, the oil settles at the bottom and will be hydrolyzed gradually. Hydrolysis produces hydrochloric acid and benzenesulfonic acid. About 5 minutes, the pH of the aqueous solution is less than 5. Complete hydrolysis to form a strong acid solution.

Main uses: for organic synthesis, preparation of sulfonamides and identification of various amines, pharmaceuticals, dyes and pesticide intermediates (manufacturing sulfonamides, etc.).
