WebEthanoic anhydride is cheaper than ethanoyl chloride. Ethanoic anhydride is safer to use than ethanoyl chloride. It is less corrosive and not so readily hydrolysed (its reaction with water is slower). Ethanoic anhydride doesn't produce dangerous (corrosive and poisonous) fumes of hydrogen chloride. Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH3CO)2O. Commonly abbreviated Ac2O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with moisture in the air. cherry\u0027s consignment idaho
