Densities of aqueous solutions of the chiral (racemic, with the enantiomer ratio of 1:1) 2-monomethylglycoluril (MMGU) and 2,4,6-trimethylglycoluril (TriMGU) have been measured using an Anton Paar DMA 5000 M densimeter. All density experiments have been performed with a precision of 0.025 kg•m −3 in the temperature range between 278.15 and 318.15 K (with a step of 10 K) at a pressure of (99.6 ± 0.08) kPa. The solute molality is in the range from 0.032 to 0.523 mol•(kg H 2 O) −1 , respectively. The temperature-dependent standard (apparent at infinite dilution) molar volumes and expansibilities of MMGU and TriMGU in water have been derived from the density data. The molar volumetric characteristics for MMGU or TriMGU as a solute in the aqueous medium have been discussed within the scope of comparative analysis including the previously obtained similar quantities for the chiral 2,6-dimethyglycoluril (trans-DMGU).

Isobaric Phase Equilibrium of tert-Butyl Alcohol + Glycerol at Local and Subatmospheric Pressures, Volumetric Properties, and Molar Refractivity from 303.15 to 333.15 K of tert-Butyl Alcohol + Glycerol, tert-Butyl Alcohol + Water, and Water + Glycerol Binary Systems

Isobaric vapor−liquid equilibrium for the binary system of tert-butyl alcohol (TBA) + glycerol were obtained at local atmospheric pressure of 95.9 kPa and subatmospheric pressures of 66.6 and 79.9 kPa over the entire composition range using a modified Othmer-type ebulliometer. Wilson and NRTL models were used for correlating the experimental data. The results suggest that the NRTL model represented the experimental data better with lower RMSD and AAD values. Furthermore, at local atmospheric pressure of 95.9 kPa, the densities and refractive indices for the three binary systems TBA + glycerol, TBA + water, and water + glycerol involved in the dehydration of TBA by extractive distillation were measured over the entire composition range from 303.15 to 333.15 K. The volumetric properties in terms of excess molar volume, partial molar volume, and isobaric thermal expansivities as well as molar refractivity were evaluated and analyzed for the three different binary systems. A Redlich−Kister polynomial was used to the fit the excess molar volume and deviations in molar refractivity. Different empirical mixing relations were also investigated for predicting the refractive indices of the three binary mixtures and are reported in terms of their average percentage deviation.
