β¦ Synopsis
All are congruently melting compounds. Compound formation is attributed to a charge-transfer interaction with the benzene, or chlorobenzene, or 1,2-dichlorobenzene, or 1,2,4-trichlorobenzene acting as electron acceptors and the nitrogen, or oxygen in N -methyl-2-pyrrolidinone acting as electron donors.

Isobaric (vapour + liquid) equilibrium (v.l.e.) of (1,3-dioxolane, or 1,4-dioxane + 1butanol, or 2-butanol) at 40.0 kPa and 101.3 kPa have been studied with a dynamic recirculating still. The experimental data for all mixtures were checked for thermodynamic consistency using the method of Van Ness.
The speed of sound, and density of the ternary {acetone + methanol + (2-methyl-1propanol, or 3-methyl-1-butanol)} were measured at T = 298.15 K, and atmospheric pressure. The experimental measurements allowed the calculation of the corresponding derived properties, as well as the analysis of the dep
Isothermal (vapour + liquid) equilibria were measured for (trichloromethane + tetrahydropyran or piperidine) at T = 333.15 K and {1-bromo-1-chloro-2,2,2-trifluoroethane (halothane) + tetrahydropyran or piperidine} at T = 323.15 K with a circulation still. The results were verified by effective stati

In this paper we report excess molar enthalpies H E m and excess molar volumes V E m of the polar solvents N -methyl-2-pyrrolidinone (C 5 H 9 NO), N ,N -dimethylformamide (C 3 H 7 NO), and dimethyl sulphoxide (C 2 H 6 SO) with 1-hexyne, or 1-heptyne, or 1octyne at T = 298.15 K. The H E m values are
