Problems solved by technology

[0002] The chemical name of hydrogen peroxide is hydrogen peroxide. Pure hydrogen peroxide is a light blue viscous liquid that can be miscible with water in any proportion. It is a strong oxidant. The aqueous solution is commonly known as hydrogen peroxide and is a colorless and transparent liquid. Disinfection, environmental disinfection and food disinfection; in general, it will slowly decompose into water and oxygen; in general, the production process of hydrogen peroxide needs to add working fluid and use ethyl anthraquinone as raw material, the performance is extremely unstable, which cannot promote the oxidation speed of hydrogen peroxide and reduce The rate of producing hydrogen from hydrogen peroxide increases the loss of medium, and the heavy aromatics in the working fluid of the traditional hydrogen peroxide production process are very easy to generate toxic substances, which increases side reactions. , which is not conducive to processing and production; in view of these defects, it is necessary to design a formula for the working fluid in the hydrogen peroxide production process

Abstract

The invention discloses a formula of a working solution in a hydrogen peroxide production process, which comprises the following components in percentage by mass: tetrahydronaphthalene, a carrier, a solvent, 2-methylcyclohexyl acetate, sulfurized oleic acid, saline water and triethanolamine, according to the following mass percentage ratio: 15-25% of tetrahydronaphthalene, 20-35% of a carrier, 15-25% of a solvent, 10-20% of 2-methylcyclohexyl acetate, 3-7% of sulfurized oleic acid, 10-20% of saline water and 6-12% of triethanolamine. The working solution is safe and reliable, and is prepared by mixing and processing a carrier formed by mixing 2-ethyl anthraquinone and tetrahydro-2-ethyl anthraquinone and a mixed solvent of trioctyl phosphate and heavy aromatics, the performance is more stable, the oxidation speed of hydrogen peroxide is greatly increased, the hydrogen production rate of hydrogen peroxide is increased and loss of theworking solution is reduced. In addition, by means ofthe distillation and continuous washing processing mode, heavy aromatics in the solvent are prevented from generation and side reactions are reduced; the method is simple and rigorous in process, cheap in raw materials, low in cost and beneficial to processing and production.
