Frequently Asked Questions (FAQs)
What is carbohydrazide used for?
Carbohydrazide is primarily used as an oxygen scavenger in industrial water treatment systems, such as boilers and cooling towers, to prevent corrosion. It also finds applications in pharmaceuticals, polymers, and aerospace as a reducing agent and propellant component.
Is Carbohydrazide safer than Hydrazine?
Yes, carbohydrazide is considered a safer alternative to hydrazine because it is non-carcinogenic and has lower toxicity. It eliminates the need for special handling precautions associated with hydrazine while providing similar oxygen-scavenging efficiency.
How does carbohydrazide work as an oxygen scavenger?
Carbohydrazide reacts with dissolved oxygen in water to form nitrogen, carbon dioxide, and water. The reaction is temperature-dependent, accelerating above 150°C, and it passivates metal surfaces to provide additional corrosion protection.
Can Carbohydrazide be used in all types of boilers?
Yes, it is suitable for high-pressure, low-pressure, and all types of boilers, including those in power generation and food processing industries, as long as dosage guidelines are followed.
How should carbohydrazide be stored?
Store carbohydrazide in airtight containers in a cool, dry environment to prevent moisture absorption and degradation. Avoid exposure to direct sunlight or incompatible materials like acids and oxidizers.
