AI Technical Summary
The use of high concentration of hydrogen peroxide in the prior art to synthesize solid peracetic acid has a risk of safety accidents, which limits its large-scale production and wide application.
Hydrogen peroxide with a mass concentration of 30-50 wt% was used for oxidation reaction, and anhydrous peracetic acid was reacted by reaction of acetic anhydride with hydrogen peroxide, and esterification was carried out with sodium perborate and acetic acid, and finally solid peracetic acid was obtained through the separation and purification step.
It reduces safety risks in the production process, simplifies process control, improves the stability and safety of solid peracetic acid, is suitable for industrial production, and reduces logistics costs and difficulty in use.
