  • Method for preparing N-oxiranemethane N,N,N-trialkylammonium compounds
    Patent number: 4582917
    Abstract: Method for preparing N-oxiranemethane N,N,N-trialkylammonium compounds by reacting epichlorhydrin with a dialkylamine to form a hydroxy compound, cooling the hydroxy compound, increasing the concentration of hydroxy ions in the reaction mixture to form a compound of the formula ##STR1## and reacting this latter compound at room temperature in acetonitrile with a benzyl compound, for example benzyl bromide.
