Structural formula
Ⅰ. Performance and use
Carbonyl hydrazine is a white crystalline powder, easily soluble in water, insoluble in alcohol, ether, benzene, because it is a derivative of hydrazine, has a strong reduction, carbonyl hydrazine has a wide range of USES in industry, in the field of water treatment can be used as boiler water deoxidizer; It can also be used as a component of rocket propellants; Because the hydrogen atom connected with nitrogen atom is easily replaced by other groups, in the textile industry, it can also be used as the crosslinking agent of elastic fiber, the capturing agent of formaldehyde, the antioxidant of pigment such as carotene. In addition, adding an appropriate amount of carbonyl hydrazine to the soap containing phenolic fungicide can prevent discoloration and rancidity. This product is non-toxic. Can replace hydrazine hydrate, oxime class. It can be used as an intermediate in the manufacture of energy-containing materials and can also be used directly as a component of rocket explosives and propellants. Carbonyl hydrazine can also be used as a crosslinking agent for elastic fibers in chemical fiber industry. As a chemical raw material and chemical intermediate, it is widely used in medicine, herbicide, plant growth regulator, dye and other industries. As a boiler water deoxidizer, low toxicity, high melting point, excellent deoxidizing efficiency, is widely used, safe and environmental protection ideal products.

Ⅲ. Use method
When making boiler deoxidizer, carbonyl hydrazine can be put into water, also can use its aqueous solution. The dosage of carbonyl hydrazine of 1molO2 was 0.5mol, and the dosage was moderately excessive. The applicable temperature range is 87.8-176.7℃. The use of carbonyl hydrazine occurs after thermal deoxygenation. The reaction of carbonyl hydrazine with oxygen is as follows: CON4H6+ 2O2= 2N2 + 3H2O + CO2
Ⅳ. Packaging and storage
Composite plastic bag packaging or packaging in line with export environmental protection requirements, each bag net weight of 25kg, can also be determined according to user requirements. Store in a cool and dry place for 12 months.
