✦ Synopsis

the excess molar volume, V m E , partial molar volumes, V m,1 °∞ and V m,2 °∞ , and excess partial molar volumes, V m,1 °E,∞ and V m,2 °E, ∞ at infinite dilution were calculated. The V m E values were found positive over the whole composition range for all the mixtures and at each temperature studied, except for methyl acrylate + 1-butanol which exhibit negative V m E values, indicating the presence of specific interactions between methyl acrylate and 1-alkanol molecules. The deviations in V m E values follow the order:

values depend upon the length of alkyl chain in 1-alkanols and the interactions between methyl acrylate and 1-alkanols decrease with increase in alkyl chain length.
