Carbohydrazide

Carbohydrazide is a white crystalline powder that is highly soluble in water and alcohols. It is commonly employed in boiler water treatment, pharmaceutical synthesis, and polymer production. This compound decomposes to release nitrogen gas, carbon dioxide, and ammonia, making it ideal for oxygen removal without leaving harmful residues.

Technical Specifications

Packaging and Storage

• Net weight 25kg in kraft bag.

• Store in a ventilation, low-temperature and dry place.

Benefits of Using Carbohydrazide

Safety Advantage: Lower toxicity profile (LD50 > 5,000 mg/kg oral, rat) compared to hydrazine, reducing handling risks.

Efficiency: Reacts rapidly with dissolved oxygen at temperatures above 80°C, achieving scavenging rates of 99%+ in boiler systems.

Environmental Friendliness: Biodegradable decomposition products (N₂, CO₂, NH₃) minimize ecological impact.

Cost-Effectiveness: Requires lower dosages (typically 1-2 ppm) than alternatives, lowering operational costs by 15-20%.

Versatility: Compatible with a wide pH range (5-11), suitable for diverse industrial setups.

Applications of Carbohydrazide

Carbohydrazide is a multi-functional chemical with applications across several industries:

Boiler Water Treatment: 

Acts as an oxygen scavenger to prevent corrosion in high-pressure boilers, extending equipment lifespan by up to 30% compared to traditional methods.

Pharmaceutical Intermediates: 

Used in the synthesis of pharmaceuticals, including anti-tuberculosis drugs and other hydrazide derivatives.

Polymer and Resin Production: 

Serves as a cross-linking agent in epoxy resins and polyurethanes, enhancing material strength and durability.

Rocket Propellants: 

Functions as a reducing agent in bipropellant systems, providing a non-toxic alternative to hydrazine.

Photography and Dye Industries: 

Employed as a developer and stabilizer in photographic emulsions and dye manufacturing.

In environmental applications, carbohydrazide helps reduce oxygen levels in wastewater treatment, promoting anaerobic processes without introducing volatile organic compounds (VOCs).

Frequently Asked Questions (FAQs)

Q: What is carbohydrazide used for?
A: 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.

Q: How does carbohydrazide work as an oxygen scavenger?

A: 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.

Q: Can Carbohydrazide be used in all types of boilers?
A: 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.

Q: How should carbohydrazide be stored?
A: 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.
