Application of 2-ethylanthraquinone in hydrogen peroxide production

The application of 2-ethylanthraquinone in the production of hydrogen peroxide is mainly as a carrier, hydrogenation reaction under the catalysis of palladium catalyst, and then the synthesis of hydrogen peroxide (commonly known as hydrogen peroxide) through oxidation reaction.

Anthraquinone process is one of the most mature hydrogen peroxide production methods in the world, which has absolute advantages. In China, this method has almost completely replaced other production processes and become the mainstream technology. The key is to synthesize hydrogen peroxide by hydrogenation and oxidation using alkyl anthraquinone derivatives as carrier. In this process, 2-ethylanthraquinone plays a key role. Specifically, the working liquid was prepared with 2-ethylanthraquinone as carrier, aromatic hydrocarbon and trioctyl phosphate as solvent. The working liquid is hydrogenated with hydrogen in a fixed bed at a certain temperature and pressure under the catalysis of palladium catalyst. Subsequently, the hydrogenated working liquid is oxidized with oxygen in the air, and finally hydrogen peroxide is obtained by extraction and purification.
