1-Hexadecanamine, N-hexadecyl- - References
| production method | (1) nitrile catalytic hydrogenation method. From the corresponding nitrile in the presence of nickel catalyst (nickel catalyst dosage of 0.4%), about 200~230 deg C, 2MPa pressure hydrogenation. Since ammonia has an inhibiting effect on the formation of secondary amine, it is necessary to remove the produced ammonia from the reactor while reacting so that the secondary amine can be obtained in a high yield. (2) secondary amines can also be produced by dehydration of higher alcohols and ammonia with a hydrogenation catalyst such as nickel and cobalt at atmospheric pressure. Ammonia gas or a mixed gas of ammonia and hydrogen may be introduced into the reaction liquid phase or circulated through the reaction liquid, and the reaction may be carried out while continuously removing water produced by the reaction. It has been reported that the hydrophosphonium dehydrogenation catalytic type can improve the yield of secondary amine in combination with a base, for example, using framework nickel and sodium carbonate as a catalyst. |
