ABSTRACT:
In the preparation of normally liquid polyether polyols for use in the production of polyurethane foams, alkaline or basic catalysts, such as potassium hydroxide, which are employed in the process of preparing said polyether polyols, are neutralized with (a) oleic acid or with (b) oleic acid and higher molecular weight alkylbenzene or alkyltoluene sulfonic acids such as dodecylbenzene sulfonic acids and dodecyltoluene sulfonic acids, or such alkylnaphthalene sulfonic acids as butyl- or amylnaphthalene sulfonic acids, which results in a number of advantages, including reducing or eliminating purification procedures, producing polyether polyol compositions which have improved solubility, particularly in higher molecular weight polyols or polyol ethers and also in certain ingredients used in the polyurethane foam formulations in which said specially neutralized polyether polyols are used, and reducing catalyst costs in the process of producing polyurethane foams from said polyether polyol compositions.
