Abstract Saturated fatty acid methyl esters from acetate to arachidate, methyl oleate, linoleate, linolenate, and erucate have been prepared in high purity. Densities, refractive indices, dispersions, ultrasonic sound velocities, and dielectric constants have been measured in the liquid state at 20 and 40C. In this first communication, the densities of the saturated compounds have been correlated with the Smittenberg relation. The following relations were derived: d 20 4 = 0.85407 + 0.18494/ (n + 0.096) and d 40 4 = 0.84225 + 0.12904/(n‐0.408). Molar volumes have been computed and checked for additivity.
