  • Catalytic process for preparing N,N-dimethylglucamine from N methylglucamine
    Patent number: 10766853
    Abstract: The invention relates to a method for preparing aqueous solutions of N,N-dimethylglucamine, characterized by first preparing an adduct of N-methylglucamine and formaldehyde in water at temperatures of between 15° C. and 40° C., and subsequently reacting said adduct to N,N-dimethylglucamine in the presence of a metal catalyst under hydrogen pressure at 20-68° C., followed by secondary hydrogenation at 70-120 bar and 70-110° C. once hydrogen absorption at 20-68° C. is completed.
    Type: Grant
    Filed: February 28, 2018
