| titleOfInvention | Method for producing alkanolamines |
| abstract | The present invention provides a method for producing ethanolamines whereby it is possible to keep the yield of dialkanolamines low (for example, less than 30% by weight). This method for producing alkanolamines involves reacting an alkylene oxide and ammonia to obtain a reaction product comprising monoalkanolamines, dialkanolamines, and trialkanolamines, separating the dialkanolamines from the reaction product, and recycling at least a portion of the dialkanolamines to the reaction of the alkylene oxide and ammonia. In the recycling step, the dialkanolamines are supplied such that the molar ratio of the alkylene oxide (mol) relative to the total amount (mol) of the ammonia and the dialkanolamines is 0.08 to less than 0.26. |
