Hydrazine hydrate is used as a polymerization inhibitor, particularly in the context of vinyl chloride monomer (VCM) storage and transportation. Here's how it functions:
1. Prevention of Uncontrolled Polymerization:
Vinyl chloride monomer (VCM) has a tendency to undergo spontaneous polymerization, which can be dangerous due to the exothermic nature of the reaction. This can lead to rapid temperature increases, pressure buildup, and even explosions.
2. Mechanism of Action:
Hydrazine hydrate acts as a free radical scavenger. It reacts with free radicals that initiate the polymerization process, thereby preventing the chain reaction from starting or continuing.
The chemical reaction between hydrazine hydrate and free radicals can effectively break the chain of polymerization, keeping VCM in its monomeric form.
3. Usage in Industry:
In industrial settings, small amounts of hydrazine hydrate are added to VCM to inhibit unwanted polymerization during storage and transport.
Typically, the concentration of hydrazine hydrate added is very low (often measured in parts per million).
4. Safety Considerations:
While hydrazine hydrate is effective, it must be handled with care due to its toxicity and reactivity. Proper safety protocols should always be followed when using this compound.
In summary, hydrazine hydrate serves as an essential inhibitor in the handling of vinyl chloride monomer by preventing uncontrolled polymerization, ensuring safer storage and transportation.
