Abstract
In the continuous process for preparing alkylamines by reacting C1-4-alkanols with ammonia in the gas phase in the presence of a shape-selective fixed-bed catalyst in a cooled reactor, the shape-selective fixed-bed catalyst is present in a single contiguous fixed bed in the reactor and tubes through which coolants are passed run within the fixed bed to regulate the temperature of the fixed bed.
Claims16
A continuous process for preparing alkylamines by reacting C1-4-alkanols with ammonia in the gas phase in the presence of a shape-selective fixed-bed catalyst in a cooled reactor, wherein the shape-selective fixed-bed catalyst is present in a single contiguous fixed bed in the reactor and tubes through which coolants are passed run within the fixed bed to regulate the temperature of the fixed bed.
A reactor for the reaction of C1-4-alkanols with ammonia in the gas phase for preparing alkylamines, which comprises a shape-selective fixed-bed catalyst which is present as a single contiguous fixed bed in the reactor and through whose interior tubes through which a coolant can be passed run.
canceled
A continuous process for preparing alkylamines by reacting C1-4-alkanols with ammonia in the gas phase in the presence of a shape-selective fixed-bed catalyst in a reactor, wherein part of the C1-4-alkanols, the ammonia or mixtures thereof is introduced in liquid form into the reactor in such a way that vaporization takes place on the fixed catalyst bed.
7-10. (canceled)
A continuous process for preparing alkylamines by reacting C1-4-alkanols with ammonia in the gas phase in the presence of a shape-selective fixed-bed catalyst in a reactor, wherein 30-90% of the C1-4-alkanols, the ammonia or mixtures thereof introduced into the reactor is fed into the fixed catalyst bed at least one point at which a previously reacted reaction mixture of C1-4-alkanols and ammonia which has a temperature higher than that of the C1-4-alkanols, ammonia or mixtures thereof fed in is present.
A continuous process for preparing alkylamines by reacting C1-4-alkanols with ammonia in the gas phase in the presence of a shape-selective fixed-bed catalyst in a reactor, wherein a heat transfer medium which is inert toward the C1-4-alkanols and ammonia and the reaction products and/or does not significantly affect the activity and selectivity of the catalyst is additionally fed into the fixed catalyst bed by addition to the reactor feed mixture.
