Notes
Why Hydrazine is replace by Carbohydrazide ?
Carbohydrazide (CH6N4O) - RXSOL-42-2541-025 is an oxygen scavenger often added to boiler systems to control corrosion. It reacts with oxygen at low temperatures and pressures. It also passivates metal surfaces preventing further corrosion. The reaction products are volatile, so they do not contribute to dissolved solids in the system. Carbohydrazide is widely used to replace hydrazine as an oxygen scavenger because it is less toxic.
