Acetylation of aniline NH H aniline (nucleophile) CH3 O O O H3C δ-δ+ acetic anhydrie (electrophile) H N CH3 O acetanilide CH3 H O + acetic acid Both aniline and acetic anhydride are somewhat viscous liquids. So, simply mixing them together does not result File Size: KB. Aniline is metabolised to different metabolites by N-acetylation (acetanilide), aromatic hydroxylation (2- and 4-aminophenol) and N-hydroxylation to N-phenylhydroxylamine which is responsible for the formation of methaemoglobin The metabolites are. The filtered solution containing the purified amine is then sufficiently pure to use in the acetylation reaction. Adding the acetic anhydride and sodium acetate begins the acetylation reaction. According to the literature for the acetylation of aniline, this as all that is necessary to complete the reaction, but in our hands, the reaction was not complete after 2 hours.

Fine molecular tuning at position 4 of 2H-chromenone derivatives in the search of potent and selective monoamine oxidase B inhibitors. Note: Alternatively, the crude acetanilide may be recrystallised from boiling water, but in this case a much greater volume about ml of the solvent will be required. Characterization Both products of part 1 and 2 should be characterized by TLC. Acetic anhydride, an anhydride of acetic acid, acts here as a source of acyl group. By Gabriele Murineddu.J. Chem. Sci.
