Process for preparing alkanolamines |
| abstract |
A process for preparing alkanolamines which comprises steps of reacting ammonia with an alkylene oxide in the presence of a carbonate of ammonia to obtain a crude alkanolamine solution, distilling off ammonia, carbon dioxide and water to regulate the content of carbon dioxide in the crude alkanolamine solution to 1% by weight or less, and distilling the crude alkanolamine solution to separate and collect the alkanolamines, whereby the production ratio of a monoalkanolamine can be increased and impurities can be decreased. |
