abstract Despite their interest for the understanding of the low-temperature behavior of biodiesel, data on the phase equilibria of biodiesels at temperatures below the cloud point are not available in the literature. To overcome this limitation, the liquid- and solid-phase compositions and fractions at temperatures below the cloud point were studied for three commercial diesels at temperatures ranging from 260 to 275 K. A thermodynamic framework able to describe these multiphase systems is presented. Two versions of the predictive UNIQUAC model along with an approach assuming complete immiscibility of the compounds in the solid phase are evaluated with success against the experimental phase equilibrium data measured in this work.
