发明名称 Process for the manufacture of alkylaminoalkanol
摘要 Color-stable alkylaminoalkanol is prepared by adding, prior to stripping-off excess reactant, an alkali metal borohydride to the reaction product of alkylene oxide and an excess of primary or secondary amine and thereafter distilling the reaction mass to recover residual and reacted (borates) alkali metal borohydride and reduced color-forming bodies as bottoms and alkylaminoalkanol as distillate. If water is present in the reaction between the alkylene oxide and primary or secondary amine, the reaction mass is distilled after recovery of excess amine to recover an azeotrope of the product which is recycled to the reactor.
