Properties and stability
Avoid light and contact with strong oxidants and strong alkali.
Storage method
Usually products contain polymerization inhibitors. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 28℃. Keep container tightly sealed. They should be stored separately from oxidants and acids, and avoid mixed 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
None
Purpose
Used as chemical intermediates.
