METHOD FOR PRODUCING PRIMARY ALIPHATIC AMINES FROM ALDEHYDES.

摘要

The invention relates to a continuous method for producing primary aliphatic amines having 9 to 18 carbon atoms in the molecule by the reductive amination of the corresponding aliphatic aldehydes. The reaction occurs without solvent in the liquid phase, wherein the feedstock aldehyde is reacted with hydrogen and ammonia in the presence of a hydrogenation catalyst at a temperature of 100 to 200°C and at a pressure of 6 to 11 MPa and at least 30 moles of ammonia are used per mole of feedstock aldehyde.
