Binary freezing point data are presented for methyl and ethyl stearate with stearic acid, methyl palmitate with palmitic acid, and methyl oleate with oleic acid. Simple eutectic points were observed for each of the systems. Oleic acid crystallized only as the low melting polymorph between ca. 11 and 90%, whereas both the low and the high melting polymorphs of oleic acid could be obtained at concentrations between 0 and 11% and 90 and 100% oleic acid.
