Excess Enthalpies of Binary Liquid Mixtures of γ-Butyrolactone + Benzene, + Toluene, + Ethylbenzene, and + Carbon Tetrachloride, and Excess Volume of the γ-Butyrolactone + Carbon Tetrachloride Liquid Mixture

Molar excess enthalpies of binary liquid mixtures of γ-butyrolactone + benzene, + toluene, + ethylbenzene, and + carbon tetrachloride were measured by means of a flow microcalorimeter of Picker type at 293.15 K. For the γ-butyrolactone + carbon tetrachloride mixture the molar excess volume was determined from density measurements at 293.15 K and 313.15 K. All measurements were performed at atmospheric pressure.
