Abstract

The invention discloses a method for synchronously synthesizing hydrogen peroxide and peroxyacetic acid, wherein, hydrogen and oxygen are taken as gas sources, alcohol, water and acetic acid are taken as reaction solvent, and phosphoric acid and salt or acid which can generate Br- after being dissolved are taken as reaction assistants; and hydrogen peroxide and peroxyacetic acid can be synthesized synchronously under the conditions that the pressure ranges from 1 to 20 MPa and the temperature ranges from minus 20 to 15 DEG C. The mixed solution that is prepared according to the method can be used as raw material for preparing compound disinfectant and bleaching agents and can also be used as intermediates for other chemical synthesis.

Description

technical field

[0001] The invention relates to a method for synchronously synthesizing hydrogen peroxide and peracetic acid. Background technique

[0002] At present, the synthesis method of industrial hydrogen peroxide is mainly anthraquinone cyclic hydrooxidation method (referred to as anthraquinone method). Its main process: the working solution containing anthraquinone and tetrahydroanthraquinone undergoes hydrogenation reaction in the presence of a catalyst, the hydrogenated working solution enters the oxidation tower, and is oxidized with compressed air, and the oxidized working solution enters the extraction tower for extraction. Hydrogen peroxide is extracted with deionized water, and the working solution flowing out of the extraction tower undergoes a series of treatments before hydrogenation. The aqueous hydrogen peroxide solution obtained from the extraction tower generally contains more impurities and needs to be purified. The entire process includes hydrogenat...
