Abstract Excess molar enthalpies H E at atmospheric pressure and 303.15 K, and static dielectric constants, ϵ s , at 2 MHz and temperature ranging from 293.05 to 323.25 K, have been determined for n‐dodecane + n‐propylamine, + n‐butylamine, + n‐hexylamine, + n‐octylamine, + n‐decylamine, + n‐dodecylamine and + pentadecylamine. From the experimental results, the variation of H E and ϵ E s with the chain length of the amine is shown.
