Dynamic viscosity coefficients are reported on n‐dodecanoic, n‐tetradecanoic, n‐hexadecanoic, and n‐octadecanoic acids and their binary systems at several temperatures from 70 to 90 C, and on their ternary and quaternary systems at 70 and 90 C. According to experimental data, liquid systems of normal fatty acids obey the “principle of congruence” in the sense that the viscosity of a mixture depends only on its average chain length.
