Vapor Pressures and Enthalpies of Vaporization of a Series of the Symmetric Linear n-Alkyl Esters of Dicarboxylic Adds
Vapor pressures and the molar enthalpies of vaporization of the linear aliphatic alkyl esters of dicarboxylic acids R CO2-(CH2)(n)-CO2-R with n = (0 to 4) with R = C2H5, n-C3H5, and n-C4H9 have been determined using the transpiration method. A linear correlation of enthalpies of vaporization (at T = 298.15 K) of the esters with the number n and with Kovat's indices has been found, proving the internal consistency of measured data.
