Abstract: Polyether polyols and their method of preparation are disclosed. The polyether polyols are prepared by reacting polyhydric alcohols with an alkylene oxide in the presence of an alkaline catalyst. The reaction mixture is then treated with a hydroxy-carboxylic acid so as to neutralize the alkaline catalyst and form a clear reaction mixture without otherwise removing the alkaline catalyst. The polyether polyols are useful for the production of polyurethane foams.
