Synthesis On Hydrazine Hydrate And Study On Its Production Techniques

Hydrazine hydrate is a widely used industrial chemical. Commonly used in the production of anti-TB medicine industry, anti-diabetes drugs, pesticide industry for the production of herbicides, plant growth regulators, bacteria, pesticides and rodent such as medicine, chemical industry for the synthesis of various types of blowing agents, boilers and response kettle off the oxygen and carbon dioxide cleaning treatment agent, commonly used in the production of military industry, rocket propellant, rubber additives and fuel cells. At present, the technical route of hydrazine hydrate backward industry, pollution, high cost, production can not meet downstream needs, long-term dependence on imports and other issues. Therefore, the study of cleaner production process of hydrazine hydrate Hydrogen peroxide is not only an important academic significance, but also has broad application prospects.This dissertation work in our group based includes the following elements:1.Azine Synthesis and Process DevelopmentUse acetonile, acetamide as catalyst, sodium hexametaphosphate as hydrogen peroxide stabilizer conditions, acetone or methyl ethyl ketone, ammonia, hydrogen peroxide as raw materials, on the selected optimum conditions get acetone azine or methyl ethyl ketone azine. Design and development of the annual output of 5,600 tons of methyl ethyl ketone azine process.2.Synthesis of hydrazine hydrate and Process DevelopmentOn the selected optimum conditions, hydrolysis the acetone azine and methyl ethyl ketone azine for hydrazine hydrate. Design and development of the annual output of 5,000 tons of 40% hydrazine hydrate solution process.
