摘要: There is provided a process for producing a (poly)alkylene glycol monoalkyl ether from an olefin and a (poly)alkylene glycol at a high conversion at a high selectivity. This process comprises reacting an olefin with a (poly)alkylene glycol in the presence of a crystalline metallosilicate as a catalyst.

摘要: 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.

摘要: A method for producing an alkanolamine from liquid ammonia in the presence of a solid catalyst efficiently with both the cost of equipment and the expense of utility repressed is provided. After not less than 60% of the ammonia has been recovered as liquid ammonia from the product solution, the remaining ammonia is recovered as aqueous ammonia solution through the steps of stripping and absorption in water. Separately, a dialkanolamine can be selectively and efficiently produced by circulating part of the product solution to the reactor.
