Backward production capacity continues to be phased out, and acetic anhydride market concentration increases

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 and is mainly used to produce phenethyl acetate, cellulose acetate, and ronyl acetate. Products such as brain esters are used in the production of spices, medicines, dyes, etc. There are two main methods for the production of acetic anhydride, namely the acetic acid pyrolysis method and the methyl acetate oxo synthesis method. The acetic acid pyrolysis method has high investment requirements, high production costs, and high energy consumption. It is a method commonly used abroad; acetic acid Methyl ester oxo synthesis has a simple production process and less emissions of three wastes, which is the main development trend of the acetic anhydride industry.

With the rapid development of global industry and the implementation of environmental protection policies, the global acetic anhydride market structure has changed. At present, the total global acetic anhydride production capacity is 3 million tons per year. With the rapid industrial development in Asia, acetic anhydride production capacity has increased. The current production capacity accounts for more than 50% of the global total production capacity, followed by North America, which accounts for 36% of the total production capacity.

According to the “China Acetic Anhydride Industry Market Supply and Demand Status and Development Trend Forecast Report 2022-2026” released by the Industrial Research Center, my country The acetic anhydride industry has been developing for many years. In 2014, the production capacity reached its peak at about 1.4 million tons/year. However, due to the impact of environmental protection policies and fierce market competition, the domestic acetic anhydride production capacity gradually decreased. By 2020, my country’s acetic anhydride production capacity will be at About 1 million tons, the industry operating rate is about 82%.

The acetic anhydride production capacity in the world is relatively concentrated, and the production capacity of TOP10 companies accounts for about 70%. Acetic anhydride manufacturers with higher production capacity in the world include Eastman, Daicel Chemical, BP, Celanese, Ningbo Wanglong, Blackstone, etc. Acetic anhydride manufacturers in my country include Ningbo Longwang, Yankuang Lunan, Celanese, Ningbo Daan, Shandong Jiachi, Hualu Hengsheng, etc.

In recent years, my country’s acetic anhydride downstream consumption structure has also undergone tremendous changes. Although cellulose acetate is still the largest application field, its proportion has shown a downward trend, while the demand for acetic anhydride in sweeteners, medicine and other fields has shown a growing trend. With the rapid development of my country’s industry and the production of new materials with high added value, the application demand for acetic anhydride continues to rise, such as polytetramethylene ether glycol, polyimide films and other fields with huge application potential.

Industrial analysts said that acetic anhydride is a fine chemical raw material with a wide range of applications. It benefits from the development of downstream industries and the market Demand is higher. However, due to the disorderly development of the acetic anhydride industry in the early stage and the sluggish downstream industry, the current acetic anhydride production capacity is serious. Under environmental protection policies and fierce market competition, backward production capacity has been gradually eliminated, and market concentration has shown a growing trend. With the continuous development of my country’s industry, the emergence of various new materials has provided space for the application of acetic anhydride. The acetic anhydride market still has development potential in the future.
