Excess Molar Volume, Viscosity, and Heat Capacity for the Mixtures of 1,4-Butanediol + Water at Different Temperatures

Abstract

Experimental densities, viscosities, and heat capacities were measured over the entire mole fraction range for the binary mixture of 1,4-butanediol + water mixtures over a temperature range. From these data, excess molar volumes, deviations in viscosity, and excess molar heat capacities were computed. The V E, Δη, and were fitted to the Redlich−Kister equation using a multiparametric nonlinear regression analysis. Estimated coefficients and standard error values for the mixing quantities are presented. V E is negative for 1,4-butanediol + water mixtures at all temperatures and over the entire compositions. Δη vs x 1 shows sinusoidal shape. The values of are positive in the whole range of mole fraction and increase with raising temperature at constant x 1. The curve has large maximum values located in the x 1 = 0.23.

Molar heat capacities for (1-butanol+1,4-butanediol, 2,3-butanediol, 1,2-butanediol, and 2-methyl-2,4-pentanediol) as function of temperature

“…for T = 297.79 K Petit and TerMinassian gave C p,m = 178 J AE K À1 AE mol À1 ). Simultaneously, the deviations found with the data published recently by Yang et al [16] are smaller than those with recommended data [13]. The obtained deviations in our work are near the uncertainty value of 1% reported by Yang et al [16].…”

“…Table 7 com- pares the viscosity of 1,4-butanediol between 298.15 and 373 K at atmospheric pressure, which has been reported in the literature by several groups [14][15][16]. The collection of data is consistent to within approximately 3%.…”
