Overview
Carbohydrazide is a versatile chemical compound primarily used in industrial applications due to its strong reducing properties. It is a white crystalline powder that is highly soluble in water and slightly soluble in alcohol. The compound is known for its stability under normal conditions but decomposes at higher temperatures. Carbohydrazide is synthesized through the reaction of hydrazine with urea or phosgene. Its unique chemical structure makes it an effective oxygen scavenger, which is particularly useful in water treatment systems to prevent corrosion in boilers and pipelines.
Physical and Chemical Properties
Carbohydrazide has a molecular weight of 90.08 g/mol and a density of 1.34 g/cm³. It melts at 153-155 °C and decomposes before reaching its boiling point. The compound is highly soluble in water, making it ideal for aqueous applications. As a strong reducing agent, carbohydrazide reacts with oxygen to form harmless byproducts, which is why it is widely used in water treatment. It is also stable under normal storage conditions but should be kept away from oxidizing agents to prevent unwanted reactions.
Main Applications
The primary use of carbohydrazide is as an oxygen scavenger in water treatment systems, particularly in boilers and pipelines to prevent corrosion. It is more effective than traditional scavengers like hydrazine, as it does not produce harmful byproducts. Carbohydrazide is also used in the production of rocket propellants due to its high nitrogen content and reducing properties. Additionally, it serves as a reducing agent in various chemical synthesis processes, including the production of pharmaceuticals and agrochemicals.
Safety and Storage
Carbohydrazide is an irritant to skin and eyes, so it should be handled with appropriate protective equipment, including gloves and goggles. In case of contact, affected areas should be rinsed immediately with plenty of water. The compound should be stored in a cool, dry place away from oxidizing agents. Proper ventilation is essential to prevent the accumulation of dust, which can be hazardous if inhaled. Containers should be tightly sealed to avoid moisture absorption.
B2B Procurement Guide
When procuring carbohydrazide, it is crucial to verify the purity and quality of the product. Suppliers should provide a material safety data sheet (MSDS) and certificates of analysis (CoA) to ensure compliance with industry standards. Bulk purchases typically offer cost advantages, but buyers should also consider storage capabilities to maintain product integrity. It is advisable to source from reputable manufacturers with a track record of supplying high-quality industrial chemicals.
