Properties and stability
Avoid contact with strong oxidants, strong reducing agents, strong acids, and strong alkali. The chemical properties are relatively stable, but it is easily hydrolyzed in the presence of caustic alkali.
Storage method
Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃. They should be stored separately from oxidants, reducing agents, acids, etc. 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
Refining methods contain impurities such as free acids and alcohols.
Purpose
Used as a solvent for nitrocellulose and paints, and also used in spices. Used as nitrocellulose, rubber, and resin solvents. It has good moisture resistance and will not swell when used in oily primers.
