    • PURPOSE: To obtain selecting the titled compound useful as an alkyd resin coating material, a catalyst for foaming polyurethane, etc. in high yield without any by-product, by reacting dialkylamine with ethylene oxide under specific conditions through the liquid-phase semi-batch method.
      CONSTITUTION: A dialkylamine expressed by formula I (R
      1 and R
      2 are respectively 1W4C lower alkyl) is reacted with ethylene oxide to obtain a dialkylaminoethanol expressed by formula II. The reaction is carried out by the liquid phase semi-batch method in such a way that the ethylene oxide is fed continuously into a solution of the dialkylamine in a solvent to effect the reaction, and the reaction is finally stopped when the molar ratio of dialkylamine to ethylene oxide reaches at 2W3:1. By the above-mentioned method, the reaction progresses selectively and finishes without causing any reaction of ethylene oxide with the aimed compound and the solvent.
