Abstract

The invention relates to a hydrogen peroxide purification method in the process of preparing hydrogen peroxide by using an anthraquinone process. The method comprises the following steps: firstly, simultaneously feeding a hydrogen peroxide solution containing organic impurities and a solvent into a mixing device, and completely mixing; feeding the two-phase mixture into a first filter so as to remove solid particles in the two-phase mixture; then, feeding the two-phase mixture into a series-wound coalescer set so as to separate the hydrogen peroxide solution with the solvent containing organic impurities; and finally, feeding the separated hydrogen peroxide solution into a second filter so as to remove trace organic impurities in the hydrogen peroxide solution. In case of treating hydrogen peroxide solutions by using the method disclosed by the invention, the organic matter content of the hydrogen peroxide solutions can be significantly reduced.

Description

Technical field:

[0001] The invention relates to a method for purifying hydrogen peroxide in the process of preparing hydrogen peroxide by anthraquinone method. Background technique:

[0002] Hydrogen peroxide (hydrogen peroxide) is a versatile and versatile chemical. Oxidation or reduction may occur in different cases. It can be used as oxidizing agent, bleaching agent, disinfectant, dechlorination agent, can be used as rocket fuel, and can be used to produce organic or inorganic peroxide, foam plastic and other porous substances. At present, hydrogen peroxide as a strong oxidant has been widely used in pulp / paper bleaching, chemical synthesis, textile bleaching and dyeing, wastewater treatment, metal processing, microelectronics production, food packaging, medical care and cosmetics.

[0003] There are many ways to prepare hydrogen peroxide, but the current method of producing hydrogen peroxide on a commercial scale mainly adopts the auto-oxidation (AO) method of circula...
