Storage conditions    
Storage precautions Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37°C. The packaging is required to be sealed and not in contact with air. It should be stored separately from oxidants, acids, and alkalis, and avoid mixed storage. It should not be stored for a long time to avoid deterioration. 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.

Stability
1. It is volatile and toxic. It has a tendency to self-polymerize and is easily oxidized by air. After oxidation, chlorine, hydrogen chloride, phosgene, formaldehyde and peroxides are generated. At the same time, this peroxide can promote monomer polymerization. It can form copolymers with various ethylene derivatives (such as vinyl chloride, styrene, etc.). Therefore, it is necessary to add a polymerization inhibitor, or seal with an aqueous solution of nitrogen, carbon dioxide, or alkali. Copper or brass has the risk of generating explosive acetylene compounds.
