Abstract:
The present invention provides a pretreatment method to reduce saturated fatty acids of fatty acids used as feedstock when preparing ester polyols. The range of feedstock includes non-fractionated to fully fractionated feedstock. Performing some fractionation by distillation of the fatty acids derived from feedstock eliminates the need to fractionate the various ozone esters from each other before esterification. Further, the approach of the present invention is more economical and efficient than the conventional method of fractionation by crystallization.
