Product Information
Hydrazine and its derivatives are used in the manufacture of herbicides and fungicides, as well as plant growth regulators. From tranquilizers to the primary drug for controlling tuberculosis, hydrazine derivatives have proven to be effective ingredients for a number of pharmaceuticals.
Used as an oxygen scavenger in boiler water, Scav-Ox® 35% hydrazine solution reduces oxidation in both low and high pressure steam systems.In fact, hydrazine is the best material that can be used for protection against oxidation in super critical boilers operating at pressures up to 3500 psi.
Currently, the plastics industry uses hydrazine derivatives in the creation of blowing agents and polymerization initiators. Use of these derivatives is also being investigated for the formulation of polymers.
Hydrazine Hydrates – Terminology
Hydrazine solution strength is usually given as the percent contained hydrazine. However, when hydrazine and water are mixed, a monohydrate (N2H4∙H20) is formed through hydrogen bonding. Therefore, the amount of hydrazine in a solution can also be designated as the percentage of hydrazine monohydrate. There is a simple relationship between the two designations, based on their molecular weights.
Hydrazine has a molecular weight of 32 and the monohydrate has a molecular weight of 50. The ratio of their weight is 32/50 or 0.64. Therefore, 100% monohydrate would contain 32/50 or 64% hydrazine. This is the reason 100% hydrazine hydrate can be used interchangeably with 64% hydrazine by weight.
To avoid confusion caused by dual terminology, Calca Solutions always expresses hydrazine content in terms of contained hydrazine. Since other companies may not follow this convention, users should ascertain which terminology applies when reference to hydrazine solution concentration is involved.
