Carbohydrazide Chemical Properties,Usage,Production

Product Features

Carbohydrazide is a white crystalline thin and short columnar crystal or white powder at room temperature. It is insoluble in alcohol, easily soluble in water with dissolution absorbing heat. It is insoluble in alcohol, ether, and benzene. Owing to that, it is a kind of derivative of hydrazine and thus having strong reduction ability. It is non-toxic, and can replace hydrazine and oximes. It has a broad range of application in industry. For example, it can be used as the oxygen scavenging agent of boiler water in the field of water treatment and is regarded as most advanced materials for oxygen scavenging of boiler water. It has a low toxicity and high melting point with its deoxidizing efficiency being far greater than the current materials used and is a idea product for both safety and environmental protection; it can also be used as a rocket propellant components; moreover, owing to that its hydrogen atoms attached to the nitrogen atom is easily substituted by other groups, it can be used as the cross-linking agents of elastic fibers in the textile field, the formaldehyde scavenger, as well as the antioxidant of carotene pigment. In addition, adding an appropriate amount of carbohydrazide to the phenol fungicides containing can play a role on preventing discoloration and rancidity. As a chemical raw material and chemical industry intermediates, it is widely used in medicine, herbicides, plant growth regulators, dyes and other industries.

Oxygen scavenger of the boiler water

When acting as the oxygen scavenger of boiler water, carbohydrazide may be directly added into the water while its aqueous solution can also be used. The usage amount of carbohydrazide for scavenging 1mol O2 is 0.5mol, and should be appropriately in excess. The proper temperature range is 87.8-176.7 ℃. The optimal time for applying carbohydrazide is after the thermal scavenging of oxygen. The reaction of oxygen and carbohydrazide is as follows: CON4H6 + 2O2 = 2N2 + 3H2O + CO2

Uses

It is widely used in the production of pharmaceuticals, herbicides, plant growth regulators, dyes, etc.(1) carbohydrazide is a derivative of hydrazine with a strong reduction. It can be not only used as the intermediates for producing energy-containing materials, but also can be used directly as the components of explosives and propellants. (2) it can be used as the preservative of refinery equipment and can also be used as the oxygen scavenger of boiler water treatment agent (3) It can be used as the cross-linking agent of the elastic fiber in the field of chemical fiber industry (4) it can be used as the chemical raw materials and chemical industrial intermediates and is widely used in medicine, herbicides, plant growth regulators, dyes and other industries.
It can be used as the component of the rocket propellant, the stabilizer of color development and soap quality, the antioxidants of rubber, the oxygen scavenger of boiler water, and the passivation agent of metal.
Carbohydrazide is a derivative of hydrazine with a strong reduction. It can be used as the intermediate of producing energy-containing materials and also be used directly for the components of explosives and rocket propellant. It can also be used as the oxygen scavenger of boiler water and is the most advanced materials for scavenging oxygen of boiler water in the world today. It has low toxicity, high melting point and a deoxidation efficiency being far greater than the materials currently used. It is an ideal product for both safety and environmental protection. In addition, it can be used as the cross-linking agent of the elastic fiber in the field of chemical fiber industry. It can also be used as the chemical raw materials and chemical industrial intermediates and is widely used in medicine, herbicides, plant growth regulators, dyes and other industries.
