Methylhydrazine(MMH) or monomethyl hydrazine, is colorless liquid of rocket propellant, having a smell of ammonia. Methylhydrazine could be used for the production of pyrazole derivatives, then form novel fungicides, herbicides and insecticides through other chemical reactions. It is also used as a rocket propellant in biopropellant rocket engines because it is hypergolic with various oxidizers such as nitrogen tetroxide (N2O4) and nitric acid (HNO3). PACKING 180KGS per Iron drum, or 20 tons per ISO tank container.
Methylhydrazine should be stored in a cool and ventilated warehouse. Keep away from fire and heat. The storage temperature should not exceed 30℃. The packing should be sealed and not in contact with air. MMH should be separated from oxidizing agents, peroxides, food chemicals, not mixed storage. Explosion-proof lighting and ventilation facilities are adopted. Do not use mechanical equipment and tools that may cause sparks. The storage area should be equipped with leakage emergency treatment equipment and appropriate storage materials.
Airtight operation, strengthen ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that the operator wear a catheter-type gas mask, a jumpsuit-type tape gas-proof suit, and rubber oil-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent the vapor from leaking into the air in the workplace. Avoid contact with oxidants. Operate and dispose in nitrogen. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C. The packaging is required to be sealed and not in contact with air. It should be stored separately from oxidants, peroxides, and edible chemicals, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials. The "five pairs" management system for extremely toxic substances should be strictly implemented.
Recently, because the price of the upstream raw material hydrazine hydrate has crazy soared, even reached at record highs. As a result, the cost of producing methylhydrazine is several times higher than before. At present, we have to suspend the production of this product and expect the raw materials to return to their original level.
