Description
Technical field
The present invention relates to a kind of dicyandiamide solution of hydrogen dioxide solution production by anthraquinone process working solution and its application.
Background technology
Hydrogen peroxide is a kind of important chemical products, is widely used in fields such as papermaking, chemical industry, food, environmental protection.Many valuable chemical products, such as inorganic peroxy acid and its salt, epoxides, organic peroxide and significant chemical reaction intermediate product can be prepared from hydrogen peroxide.Hydrogen peroxide has the selectivity more much higher than other oxidants as a kind of weaker oxidant, in organic synthesis.Hydrogen peroxide is used as bleaching agent in textile industry and paper-making industry, it is used as oxidant in chemical industry synthesis, it is used as disinfectant and bactericide in food and medicine industry, can be used to process toxic wastewater in terms of environmental protection, wherein processes at most and it is most useful that sulfide, cyanide and phenolic compound.Hydrogen peroxide can also be used to process poisonous fume, such as SO2, NO and H2S etc..Also it is used for the organic pollution oxidative degradation in water body.Hydrogen peroxide final reacting product itself is water, does not produce secondary pollution, is a kind of excellent green industry raw material and disinfectant.In recent years, as hydrogen peroxide is in environmental protection and the exploitation of other side new opplication, the demand of hydrogen peroxide increasingly increases.
Hydrogen peroxide preparation method mainly has：With carbon monoxide production peroxide passivation etc. in electrolysis, air cathode method, anthraquinone, hydrogen-oxygen direct synthesis technique, methyl-benzyl alcohol oxidizing process, isopropanol oxidation method, fuel cell method and the aqueous solution.Wherein, it is anthraquinone due to the advantages of its technology is advanced, production scale big, high degree of automation, cost and energy consumption are low, the three wastes are easy to improvement, there is greater advantage with respect to other methods.
In hydrogen dioxide solution production by anthraquinone process technique, working solution is mainly made up of the solvent of working material and dissolving working material.The production capacity of the property of solvent not only direct determination device, and to the efficiency of hydrogenation, oxidation and extracting operation process, the degraded of effective anthraquinone has considerable influence.Therefore, for the selection of solvent, typically require that it has strong to working material solvability, chemical stability is good, and the solubility in water and hydrogen peroxide is little, and, viscosity is little, low toxin with water stratification substantially.Under normal conditions, solvent is typically all and is formed by two kinds of organic solvent mixed preparings, a kind of solvent mainly as anthraquinone, it is another kind of mainly as
