Disclosed is an improvement in a process for catalytic production of methylamines from methanol and NH3, or methanol, a mixture of methylamines and NH3, or a mixture of methylamines and NH3, in a gaseous phase, over a bed of a zeolite catalyst, where the improvement is that the catalyst bed is divided into two or more sub-beds, and the difference between the inlet and outlet temperatures of each catalyst sub-bed is kept in the range of approximately 5°C to approximately 70°C while the reaction is carried out. |
