In producing alkanolamines by use of a microporous material as a catalyst, the difficulty in industrially performing the production because of the short lifetime of the catalyst is resolved. A process of regenerating the catalyst by removing an organic substance deposited on the catalyst by means of decomposing and/or extracting the substance is introduced, and thereby steady production is carried out substantially over the long term by switching the reaction and the regenerating processes.
