Acetic anhydride, also known as acetic anhydride, is a fine chemical raw material produced from carbon monoxide, acetic acid, and methanol. It is one of the simplest organic acid anhydrides, mainly used in the production of phenethyl acetate, cellulose acetate, and bornyl acetate, and is applied in the production of fragrances, pharmaceuticals, and dyes.

There are two main methods for producing acetic anhydride: acetic acid cracking (ACETEK MOMENTUM uses the acetic acid cracking process) and methyl acetate carbonyl synthesis. Acetic acid cracking requires high investment, has high production costs, and high energy consumption, and is the method commonly used abroad. Methyl acetate carbonyl synthesis has a simpler production process and produces less waste, making it the main trend in the acetic anhydride industry.

Acetic anhydride is a fine chemical raw material with a wide range of applications. Benefiting from the development of downstream industries, market demand is high. With the continuous development of China's industry and the emergence of various new materials, space is being created for the application of acetic anhydride, and the future market for acetic anhydride has broad development potential.
