a colorless, pungent liquid, C4H6O3, the anhydride of acetic acid: used chiefly as a reagent and in the production of plastics, film, and fabrics derived from cellulose. [1875–80] Random House Kernerman Webster's College Dictionary, © 2010 K Dictionaries Ltd. Copyright 2005, 1997, 1991...
mainly used for the synthesis of cellulose acetate, drugs, acetylating agents, dyes and spices acetic anhydride is an important acetylation test,, can make alcohol, phenol, ammonia and amine form acetate and acetamide compounds respectively. In the presence of Lewis acid, acetic anhydride can also...

In the presence of sodium acetate, acetic anhydride and benzaldehyde undergo condensation reaction to form cinnamic acid. Acetanhydride is used to make cellulose acetate, acetic acid plastic, non-combustible film film; in the pharmaceutical industry, it is used to make gimycin, furazol, dibazol,...
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH3CO)2O. Commonly abbreviated Ac2O, it is the simplest isolatable acid anhydride and is a widely used reagent in organic synthesis. It is a combustible, colorless, strongly refractive, liquid that smells strongly...
Acetic acid and acetic anhydride are used in the industrial synthesis of acetate monomers, esters and salts. Vinyl acetate, an important industrial monomer, is prepared from acetic acid by the Zn(OAc)2/carbon catalyzed acetoxylation of acetylene, or by Pd/CuII catalyzed acetoxylation of ethylene...

Acetic anhydride, in the presence of pyridine, reacts quantitatively with anhydrous oxalic acid to form acetic acid, carbon dioxide, and carbon monoxide. Based on this reaction, two small-scale procedures have been devised for the determination of this anhydride. The first, in adaptation of Rosenb...
