Power is strong, and chemical stability is good, and the solubility in water and hydrogen peroxide is small, and, viscosity is small, and toxicity is low excellent with water stratification substantially
Point.Under normal conditions, solvent is typically all and formed by two kinds of organic solvent mixed preparings, a kind of mainly as the molten of anthraquinone
Agent, another solvent mainly as hydrogen anthraquinone.Anthraquinone solvent mainly uses C in domestic hydrogen peroxide unit9Heavy aromatics,
Isomers wherein containing trimethylbenzene, the first and second benzene, propyl benzene and indenes etc.；Higher aliphatic, organic acid or nothing are used hydrogen anthraquinone solvent more
The esters of machine acid, industrial applications has trioctyl phosphate, diisobutyl carbinol (DIBC), methyl cyclohexanol acetate etc..Compare at present
Common solvents system is heavy aromatics and trioctyl phosphate.
In order to improve the solubility of anthraquinone, also there is the working solution using three dicyandiamide solutions.CN1552618A discloses one kind
Organic solvent system in hydrogen peroxide production process, it uses C9~C10Aromatic hydrocarbons, trioctyl phosphate and 2- methylcyclohexyl acetic acid
Ester is working solution system, improves anthraquinone solubility, improves hydrogenation efficiency.CN101798065A discloses a kind of for anthracene
Quinone method produces the Working solution prescription of hydrogen peroxide, and wherein solvent group turns into：Heavy aromatics 65%~80%, trioctyl phosphate 5%~25%,
N- phenyl N- ethyl benzamides 4.5%~17.8%, the solubility of working material is big, working solution medium density, and live load is big,
Reduce anthraquinone degradation rate.Although the anthraquinone solubility that three compositions system is improved, improves hydrogenation efficiency, third component plus
Enter, also make mixed solvent composition more complicated, while adding the production cost of hydrogen peroxide.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of working solution of hydrogen dioxide solution production by anthraquinone process and application.Should
Working solution uses two component solvent systems, improves anthraquinone solubility, improves hydrogenation efficiency, compared with three compositions system, letter
Change composition, reduce production cost.
