Abstract

The invention discloses a production process of n-hexylamine. The production process comprises the following raw materials in parts by weight: 10 to 50 parts of methyl n-hexyl ketoxime, 5 to 30 parts of diethyl ether, 15 to 35 parts of phosphorus pentachloride, 2 to 10 parts of a catalyst, 12 to 28 parts of n-hexyl alcohol, 5 to 20 parts of ammonia gas, 5 to 15 parts of hydrogen, 10 to 40 parts of caprolactam, 8 to 24 parts of sodium carbonate and 5 to 12 parts of organic solvent. The production process comprises the following steps: S1, putting methyl n-hexyl ketoxime into a first reactor, then adding diethyl ether, reacting for a period of time, then adding water, uniformly stirring, and after stirring for a period of time, adding phosphorus pentachloride to finally obtain N-acyl n-hexylamine. According to the production process of the n-hexylamine, the reaction conditions are mild, the problems existing in the production process are solved, the production route of the process is simple and optimized, the operation is simple, the production conversion rate is high, and a product with good selectivity can be finally obtained, so that the economic benefit can be greatly improved.
