A perturbed chain equation-of-state was extended to the solid-fluid equilibria (SFE) of a binary mixture of chain molecules. A volume fraction-based mixing rule was applied to combine pure component segment size, chain length, and interaction energy parameters to form parameters that characterize the binary fluid-solid system. The solid-fluid equilibria (SFE) of n-alkane mixtures were correlated well with the model using only minor reliance on one binary interaction parameter. Values of the binary parameter correlated smoothly with difference in carbon number of the mixture components demonstrating potential of the model to be able to predict multi-component SFE from pure component data alone.
