| titleOfInvention | Process for producing alkanolamines |
| abstract | The present invention provides a method for producing ethanolamines that can keep the dialkanolamine production ratio low (for example, less than 30% by weight). In the method for producing an alkanolamine of the present invention, an alkylene oxide and ammonia are reacted to obtain a reaction product containing a monoalkanolamine, a dialkanolamine and a trialkanolamine; the dialkanolamine is separated from the reaction product Recycling at least a portion of the dialkanolamine to a reaction of alkylene oxide and ammonia, wherein in the recycling step, the dialkanolamine is based on the total amount (mole) of ammonia and dialkanolamine. And supplying such that the molar ratio of alkylene oxide (mol) is 0.08 or more and less than 0.26. |
