\ | Hydrazine Hydrate and Liozan® |
Arkema is one of the world's largest producers of hydrazine hydrate. Hydrazine hydrate is a powerful reducing agent and is marketed in various concentrations (aqueous solutions from 24% to 100%):
- 24% to 55% solutions are used mainly for water and effluent treatment
- 60% to 100% solutions are used for synthesis and manufacturing of hydrazine derivatives
- Colorless liquid
- 100% soluble in water
- Strong alkaline reducer
- Stable and easy to handle
- Extremely low sodium and chloride content
- Low total organic carbon content
- Very few mineral residues and metallic impurities
Because of its unique physical-chemical properties, hydrazine hydrate has been developed for use in numerous applications.
Treatment processes
- Water treatment : hydrazine hydrate is an oxygen scavenger for water used in industrial boilers and high pressure steam generators (thermal and nuclear power plants). In this field, Liozan® is an activated form that provides faster oxygen scavenging and offers the possibility of working at lower temperatures
- Refining of precious metals and purification
- Surface treatment solutions
- Purification of sulphuric acid for grades used on the electronics market
- Metallization of plastics and metals (nickel, cobalt, iron, chromium, etc.)
- Effluents treatment (liquid and gas streams)
Hydrazine hydrate is used as a reagent for the production of :
- Bio-active intermediates for agrochemical and pharmaceutical products, also via triazoles and other hydrazine derivatives (salts)
- Polymerization initiators (azo-initiators)
- Various products: certain organic pigments for dyes, urethanes and acrylics, hydrobromic acid, reagents for photography, etc.
- Blowing agents: azodicarbonamide
