Properties and stability

Avoid light. Avoid contact with strong oxidants, strong acids, and air.

Storage method

Usually products contain polymerization inhibitors. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The storage temperature should not exceed 30℃. Keep container sealed and strictly prohibited from contact with air. They should be stored separately from oxidants, acids, etc., and avoid mixed storage. Not suitable for long-term storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method
