Storage method
Storage Precautions[23] Store in a cool, well-ventilated special warehouse, and implement the “two people to send and receive, and two people to keep” system. Keep away from fire and heat sources. The storage temperature should not exceed 37°C. Keep container tightly sealed. They should be stored separately from reducing agents, acids, alkalis, and food chemicals, 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
1. Obtained from the oxidation of butene and ammonia
2. Obtained from the catalytic oxidation of butanol and ammonia.
3. Mixed with hydrocarbons In this case, acetonitrile can be added and removed by azeotropic distillation. If it contains isonitrile impurities, use concentrated hydrochloric acid to decompose and remove them. Moisture is removed with magnesium sulfate or phosphorus pentoxide. Finally refined through distillation.
Purpose
1. Used as intermediates, raw materials for organic synthesis, solvents, and other fine chemicals.
2. Used as chemical drugs and pharmaceutical intermediates. [24]
