  • Process for the production of aminopropylmethylethanolamine
    Patent number: 9428446
    Abstract: 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.
