Abstract The production of acetic anhydride is mainly achieved by acetic acid cracking method, which has the advantages of wide source of raw materials and simple reaction process, but it also has some problems such as low product selectivity and harsh reaction conditions. In order to solve the problems, the process conditions of acetic acid cracking to produce acetic anhydride were optimized to ensure the high efficiency of the reaction, so as to achieve the goal of improving production efficiency and reducing production cost.
