Octadecanamine

CAS:: 124-30-1

MF:: C18H39N

MW:: 269.51

Use：: It can be obtained from stearic acid via ammoniation and hydrogenation. Send stearic acid and ammonia continuously and quantitatively into the liquid phase reaction tower for ammoniation at 350 ℃ to generate octadecane nitrile. After washing with water and refinement, it was sent to the autoclave and was subject to hydrogenation reaction under 130 ℃ and the pressure of about 3.5MPa with the nickel catalyst for generation of Octadecanamine. The hydrogenated product was subject to precipitation for removing the catalyst to derive the final products. During laboratory preparation, the octadecane nitrile and anhydrous ethanol are subject to boiling under reflux and further put into sodium metal for reaction. Pour the reaction mixture into the dilute hydrochloric acid with cooling obtaining the Octadecanamine hydrochloride. Further treat with 20% sodium hydroxide solution treated with 20% sodium hydroxide solution can produce Octadecanamine. The yield is 85%. Fixed consumption amount of material: stearic acid: 1165kg/t, ammonia 151kg/t, hydrogen gas: 211m3, nickel catalyst: 6kg/t.
