English name acetyl chloride; ethanoyl chloride name acetyl chloride; chloride ( of ) acetyl molecular formula C2H3ClO; CH3CClO appearance and properties colorless fuming liquid, has a strong irritating smell molecular weight 78.50 vapor pressure flash point: 4 12.1kPa/0melting point -112 boiling point : 51dissolved soluble in acetone, ether, acetic acid. Relative density ( =1 water ) 1.11; relative density ( air =1) 2.70 stability stability risk marker 7 ( flammable liquid ), 20 ( corrosive ) mainly used for organic compound, dye and medicine manufacturing industry on Preparation of acetyl chloride from ketene reacts with hydrogen chloride, or sodium, sulfur dioxide and chlorine by reaction system. The laboratory by acetic acid, acetic anhydride and sodium acetate or various chlorinating agent was prepared by the reaction of. Effects of acetyl chloride is important for the acetylation reagent, acetic anhydride acylating ability than the strong, widely used in organic synthesis. Acetyl chloride and carboxylic acids have chlorination reaction catalyst, but also can be used for the quantitative analysis of hydroxyl or amino groups.
