| 发明名称 | Process for the production of aminopropylmethylethanolamine | ||
| 摘要 | A new process for the production of APMMEA (aminopropylmethylethanolamine) is proposed. This process comprises at least 2 steps in which MEAPN (monomethylethanolaminopropionitrile) is first produced from MMEA (monomethylethanol amine) and ACN (acrylonitrile) and then said MEAPN is hydrogenated to obtain the corresponding amine, the APMMEA compound. APMMEA may be then eventually purified by several known process, notably by distillation. | ||

| 主权项 | 1. A process for the production of APMMEA comprising at least 2 steps: (a) Production of MEAPN from reaction of MMEA and ACN; (b) Hydrogenation of said MEAPN in the presence of a reaction medium comprising a catalyst, inorganic base, and water to produce APMMEA; and (c) Isolation of said APMMEA. | ||
