Acetic Anhydride is widely employed for its acetylating and dehydrating properties across the food & beverage and manufacturing industries.
What is Acetic Anhydride?Acetic Anhydride is a clear liquid with a pungent, penetrating vinegar-like odor. It is completely miscible with diethyl ether and can be easily dissolved in the usual organic solvents. Acetic Anhydride also reacts with alcohols and is an excellent solvent for numerous organic and inorganic products.
Why Acetic Anhydride?A major benefit of using acetic anhydride is its acetylation ability of cellulose properties which is needed to produce acetate fibers, plastics, coatings, and films. It is especially valuable for the direct esterification of alcohol where acetic acid cannot be used. Another large use for acetic anhydride is in the manufacture of acetylsalicylic acid (aspirin), acetylcholine hydrochloride, acetophenacetin, sulfonamides, aceto-p-aminophenol, cortisone, acetanilide, theophylline, sulfa drugs, certain vitamins, and hormones, and many other pharmaceuticals and pharmaceutical intermediates.
