Storage method
Storage Precautions[20] 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, 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
1. Obtained from methyl n-hexyl ketone oxime treated with phosphorus pentachloride. Treat methyl n-hexyl ketone oxime in diethyl ether with phosphorus pentachloride, then add water, mix well, and separate the layers. The N-acetyl n-ethylamine generated by the rearrangement is dissolved in diethyl ether, and the diethyl ether layer is separated. The ether is recovered by distillation, and the remaining oily liquid is hydrolyzed with a dilute potassium hydroxide solution and then distilled. Collect the 130-133°C fraction to obtain hexylamine.
Purpose
Used in organic synthesis. [21]
