Hydrazine Test Kits - Thermal Scientific

Hydrazine is a powerful reducing agent that is used in various chemical processes and in boiler water as an oxygen scavenger. To control corrosion, residual hydrazine typically is maintained in the 0.05 to 0.1 mg/L range. Higher levels may be used to guard against corrosion when the boiler is out of service for an extended period.

Hydrazine - Infogalactic: the planetary knowledge core

Hydrazine is an inorganic compound with the chemical formula H 2 NNH 2 (also written N 2 H 4).It is a colorless flammable liquid with an ammonia-like odor.Hydrazine is highly toxic and dangerously unstable unless handled in solution. As of 2000, approximately 120,000 tons of hydrazine hydrate (corresponding to a 64% solution of hydrazine in water by weight) were manufactured worldwide per year.

CARBOHYDRAZIDE vs HYDRAZINE: A Comparative Study

At the start with the recommended dosage of 1.5 ppm of carbohydrazide, determination of carbohydrazide in feed water was observed to give inconsistent values. The inconsistency observed was attributed to the high temperature of the feed water (235oC) because at temperatures above 150oC carbohydrazide hydrolyzes to hydrazine. 0 5 10 15 20 25 30
