在无机酸存在和常温常压下,以醋酸为酰化剂使过氧化氢乙酰化生成过氧醋酸:CH_3COOH+H_2O_2(?)CH_3COOOH+H_2O1974年美国FMC公司利用此法首先实现工业化。由于该法化学反应达到平衡时,过氧醋酸中含有大量水和酸性催化剂,所以在作为氧化剂时常常出现困难。为此,FMC公司提出以5%~20%的硫酸为催化剂,35%~55%的过氧化氢和醋酸在36~60℃连续反应10~30min的连续法,其杂质大幅度
In the presence of inorganic acid and normal temperature and pressure, acetic acid is used as an acylating agent to acetylate peroxide to produce peroxyacetic acid: CH 3 COOH + H 2 O 2 (?) CH 3 COOOH + H 2 O In 1974, FMC used this method to first realize industrialization. Since the chemical reaction of the method reaches an equilibrium, peroxyacetic acid contains a large amount of water and an acidic catalyst, so that it often occurs as an oxidizing agent. To this end, FMC Corporation proposed a continuous method of continuously reacting 10-30 min at 36-60°C with 5%-20% sulfuric acid as a catalyst, 35%-55% hydrogen peroxide and acetic acid, and the impurities are greatly reduced.
