Storage method
Storage Precautions[15] Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37℃. Keep container tightly sealed. They should be stored separately from oxidants, acids, and alkalis, 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
It is produced by the esterification reaction of n-butyric acid and n-propanol under the catalysis of sulfuric acid.
Purpose
1. Mixed solvent used for making cellulose and ether. [16]
