Problems solved by technology
[0006] The working fluid solvent system in the prior art is mostly prepared by mixing two kinds of organic solvents as in the above process, heavy aromatics are mainly used as the solvent of anthraquinone, and trioctyl phosphate is used as the solvent of hydrogen anthraquinone; The working solution of this solvent system is not high for the solubility of anthraquinone, which affects the oxidation efficiency and hydrogenation efficiency of the anthraquinone preparation hydrogen peroxide process, so it is necessary to provide a method that can effectively improve the oxidation efficiency and hydrogenation efficiency of anthraquinone preparation hydrogen peroxide process. Efficient working fluid solvent system

The present invention adopts an anthraquinone method to prepare a working solution of hydrogen peroxide, which includes a solute 2-ethylanthraquinone and a solvent system for dissolving 2-ethylanthraquinone. The solvent system includes solvent heavy aromatic hydrocarbons and trioctyl phosphate. , o-methylcyclohexyl acetate, the volume ratio of the heavy aromatic hydrocarbon, trioctyl phosphate, o-methylcyclohexyl acetate is 78:23:8. The working fluid designed by the present invention can replace part of trioctyl phosphate with o-methylcyclohexyl acetate, which can effectively improve the solubility of anthraquinone in the working fluid solvent system, thereby improving the oxidation efficiency and hydrogenation efficiency, and can effectively improve the preparation of hydrogen peroxide. The single output of the process can effectively reduce production costs.
Description
technical field [0001] The invention belongs to the technical field of hydrogen peroxide preparation, and in particular relates to a working solution for preparing hydrogen peroxide by an anthraquinone method and an application thereof. Background technique [0002] Hydrogen peroxide is an aqueous solution of hydrogen peroxide. Hydrogen peroxide is an important chemical product widely used in papermaking, food, environmental protection and other fields. Hydrogen peroxide is also used as a bleaching agent in the textile and paper industries, as an oxidizing agent in chemical synthesis, as a disinfectant and bactericide in the food and pharmaceutical industries, and can also be used to treat toxic waste gases in terms of environmental protection, such as sulfur dioxide, a Nitrogen oxides, hydrogen sulfide, etc. Moreover, the final product of hydrogen peroxide is water, which does not cause secondary pollution to the environment, and is an excellent green industrial raw materi...
