Abstract:
A process for modifying an unsaturated triacylglycerol oil comprising:reacting an unsaturated triacylglycerol oil having an Iodine Value of no more than about 150 and an active methylene content of no more than about 1.5 with an hydrocarbon diene and at a temperature of at least about 200Â° C. to form a cycloaddition product comprising triacylglycerol which have at least one unsaturated fatty acyl chain modified to include a cycloaddition adduct, wherein the cycloaddition product has a viscosity at 40Â° C. of no more than about 200 cP and an AOM value of at least about 50 hours; and at least partially hydrogenating the cycloaddition product in the presence of a hydrogenation catalyst to form a partially hydrogenated cycloaddition product having an Iodine Value of no more than about 150 and an active methylene content of no more than about 1.5.
