Speeds of sound in and isentropic compressibilities of (1,1,2,2,-tetrachloroethane + anisole, 1,4-dioxane, methylethylketone, and pyridine) atT= 303.15 K

Speeds of sound and isentropic compressibilities of (cyclohexanone + dichloromethane, or trichloromethane, or trichloroethene, or 1,2-dichloroethane) atT= 303.15 K

“…The same sequence has also been found (1,3) for the values of V E m at x = 0.5 for {xC 6 and {xC 6 H 10 O + (1 − x)CHClCCl 2 } indicate also the formation of intermolecular complexes between the components of these mixtures. The values of κ E S for {xC 6 H 10 O + (1 − x)CHClCCl 2 }, and {xC 6 H 10 O + (1 − x)CH 2 Cl 2 }, which are less negative as compared with the values of κ E S for {xC 6 H 10 O + (1 − x)CHCl 3 }, may be attributed to a predominance of contributions to κ E S from physical interactions over specific interactions.…”

“…The values of κ E S of the various mixtures obtained through equation (6) have been fitted using a method of least-squares to the Redlich-Kister (14) type equation:…”

Excess molar volumes, speeds of sound and isentropic compressibilities of (1,4-dioxane + trichloromethane, or tetrachloromethane, or 1,1,2,2-tetrachloroethane, or 1,1,1-trichloroethane) atT = 293.15

“…Nath (4) has also measured the vapour pressures of these mixtures. In addition, Nath and Pandey (5) have measured V E m , and Nath (6) …”

Excess Molar Volumes, Relative Permittivities, and Refractive Indexes of 1,1,2,2-Tetrachloroethane + Pyridine, +Anisole, +Methyl Ethyl Ketone, and +1,4-Dioxane at 303.15 K

“…1,4-Dioxane was stored over sodium wire and was used. The densities of these purified samples of the various liquids were measured using a single-capillary pycnometer and have been reported recently (Nath, 1996) as 0.972 86, 0.984 64, 0.794 49, 1.022 32, and 1.578 57 g‚cm -3 for C 5 H 5 N, C 6 H 5 OCH 3 , CH 3 COC 2 H 5 , 1,4-C 4 H 8 O 2 , and CHCl 2 CHCl 2 , respectively, at T ) 303.15 K, as compared with the corresponding literature (Timmermans, 1950) values 0.972 81, 0.984 62, 0.794 52, 1.022 30, and 1.578 60 g‚cm -3 for the various liquids in the same order.…”
