METHODS OF MAKING TRIACYLGLYCEROL POLYOLS FROM FRACTIONS OF METATHESIZED NATURAL OILS AND USES THEREOF

摘要

The instant application is directed to methods of making triacylglycerol polyols from natural oil. Said methods comprise providing a metathesized triacylglycerol composition formed by cross-metathesis of natural oil with lower-weight olefins, and comprising triglyceride compounds having one or more carbon-carbon double bonds; separating a fraction of the metathesized triacylglycerol composition to form a fractionated metathesized triacylglycerol composition which comprises triacylglyceride compounds having one or more carbon-carbon double bonds; and reacting at least a portion of the carbon-carbon double bonds of the triacylglyceride compounds having one or more carbon-carbon double bonds present in the fractionated metathesized triacylglycerol composition to form a triacylglycerol polyol composition. Polyurethanes made using the triacylglycerol polyols are also disclosed, as well as waxes and foams comprising the same.
