| description | 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. |
