Hydrazine hydrate 55% is an aqueous solution of hydrazine (N₂H₄) widely used as a corrosion inhibitor and reducing agent in industrial applications. This product is highly corrosive and toxic and requires strict safety protocols for handling. The 55% concentration is also referred to as 35% hydrazine, as the percentage refers to the different molecular forms present.
Common applications
- Corrosion control: 55% hydrazine hydrate is commonly used as an oxygen scavenger in industrial boilers, nuclear power plants, and other high-pressure steam systems to prevent corrosion.
- Blowing agent: It is used to produce polymer foams, such as PE, PVC, and EVA.
- Chemical synthesis: It serves as an intermediate for producing agrochemicals, pharmaceuticals, and dyes.
- Precious metal refining: Hydrazine hydrate acts as a reducing agent in the purification of precious metals.
- Water treatment: It is used to remove lime scale and heavy metals.
