    摘要： A process for preparing an N,N-dialkylethanolamine of the formula I having high color stability where R1 and R2 are each independently a C1- to C8-alkyl group, by reacting ethylene oxide (EO) with a corresponding dialkylamine (R1R2NH) in the presence of water, wherein the reaction is effected continuously in a reactor, the reaction temperature is in the range from 90 to 180° C. and the residence time (RT) in the reactor is in the range from 1 to 7 min, the reactor output is treated thermally at a temperature in the range from 80 to 160° C. over a period in the range from 20 to 1000 min, and then the N,N-dialkylethanolamine is removed by distillation.
