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.
