Abstract

The invention discloses an oxidative extraction method for hydrogen peroxide preparation through an anthraquinone process and a method for producing hydrogen peroxide. The oxidative extraction method comprises the steps: making a hydrogenation liquid containing alkyl hydrogen anthraquinone, oxygen-containing gas and water contact in a fibrous membrane contactor, and carrying out oil-water separation of the obtained mixture. While the fibrous membrane contactor is adopted for implementing the method, oxidation and extraction for hydrogen peroxide preparation through the anthraquinone process are carried out, so that the productive quality of hydrogen peroxide is improved, and production equipment of hydrogen peroxide is reduced.

Description

technical field [0001] The invention relates to a process for producing hydrogen peroxide by an anthraquinone method, in particular to an oxidative extraction method for producing hydrogen peroxide by an anthraquinone method, and a method for producing hydrogen peroxide. Background technique [0002] As an important chemical, hydrogen peroxide is widely used in various fields of national production and life. The anthraquinone method is the mainstream process for the production of hydrogen peroxide in the world, which includes hydrogenation, oxidation, extraction and post-treatment processes. An important step in hydrogen oxidation, the process has a major impact on improving the oxidation efficiency, maintaining the stability and safety of the reaction. [0003] At present, in the production process of hydrogen peroxide produced by anthraquinone method, the oxidation and extraction steps are respectively completed step by step in two different production devices. The oxida...
