| titleOfInvention | Production method of alkanolamines |
| abstract | The present invention provides a method for producing ethanolamines that can suppress the production ratio of dialkanolamines at a low level (eg, less than 30% by weight). The method for producing alkanolamines of the present invention includes the steps of: reacting an alkylene oxide and ammonia to obtain a reaction product containing monoalkanolamine, dialkanolamine, and trialkanolamine; and separating from the reaction product The process of dialkanolamine; the process of recycling at least a part of the dialkanolamine in the reaction of alkylene oxide and ammonia; and the recycling process includes: the alkylene oxide (mol) relative to ammonia and The dialkanolamine was supplied so that the molar ratio of the total amount (mol) of the dialkanolamine was 0.08 or more and less than 0.26. |
