Densities for binary mixtures of three alkanols (1,2-propanediol, 1,3-propanediol, and ethane-1,2-diol) with 1,4-butanediol over the whole composition range have been measured at temperatures from (293.15 to 328.15) K in 5 K intervals. From these data, the excess molar volumes (V-E) and their standard deviations sigma(V-E) were calculated. The experimental results were fitted to the Redlich-Kister equation using a multiparametric nonlinear regression analysis.
