Abstract

Vapor pressures and the molar enthalpies of vaporization of the linear aliphatic alkanediamines H 2 N–(CH 2 ) n –NH 2 with n = (3 to 12) have been determined using the transpiration method. A linear correlation of enthalpies of vaporization (at T = 298.15 K) of the alkanediamines with the number n and with the Kovat’s indices has been found, proving the internal consistency of the measured data.
