Thanks to the development of personal computers and software, it is often faster and, therefore, cheaper to calculate product properties than to determine them analytically, but such calculations are only possible after the appropriate mathematical equations have been formulated. Formulating these equations may use some assumptions and parameters that have been determined experimentally. This article describes a method of calculating the composition of the ester interchange reaction product of triacylglycerol oil with glycerol and/or propylene glycol; it can be extended to include further polyols. The calculation requires the composition of the starting material, the saponification and hydroxyl values of the oil, and three parameters indicating how the fatty acid distribution in the reaction product deviates from random. These parameters are not known but can be quantified by combining the method of calculation described in this article and some analytical results.
