The properties of binary mixtures of tetramethylmethane, tetramethylsilane, and tetramethylstannane

The properties of binary mixtures of tetramethylmethane, tetramethylsilane, and tetramethylstannane. II. Excess Gibbs functions. Brewster, E.; McGlashan, M. L. (Dep. Chem., Univ. Coll. London, London, Engl.). J. Chem. Thermodyn., 9(11), 1095-9 (English) 1977. CODEN: JCTDAF. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Section cross-reference(s): 29 The excess molar Gibbs function GmE was measured as a function of mol fraction at 279.95 K for each of the binary liq. mixts. formed from Me4C [463-82-1], Me4Si [75-76-3], and Me4Sn [594-27-4]. A previously described method, in which GmE was derived from measurements of the dew pressure pd and the mol fraction y in the gaseous phase, was used. GmE is always pos. and increases in the same sequence as HmE. Comparison of the results with theories depending on the principle of corresponding states is deferred until the results of measurements of the crit. quantities have been presented.

The properties of binary mixtures of tetramethylmethane, tetramethylsilane, and tetramethylstannane

The properties of binary mixtures of tetramethylmethane, tetramethylsilane, and tetramethylstannane. I. Excess enthalpies and excess volumes. Ahmed, A.; Dixon, D. T.; McGlashan, M. L. (Dep. Chem., Univ. Coll. London, London, Engl.). J. Chem. Thermodyn., 9(11), 1087-93 (English) 1977. CODEN: JCTDAF. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Section cross-reference(s): 68 The excess molar enthalpy HmE and excess molar vol. VmE were measured as a function of mole fraction at about 283 K for each of the binary liq. mixts. formed from Me4C [463-82-1], Me4Si [75-76-3], and Me4Sn [594-27-4]. For tetramethylmethane + tetramethylsilane HmE and VmE are both pos.; for the other two mixts. HmE is pos. while VmE is neg. Comparison of the results with theories depending on the assumption of the principle of corresponding states is deferred until the results of measurements of GmE and measurements of the crit. quantities are presented. Some of the isothermal-jacket-calorimetric measurements of HmE reported were made by deliberately arranging for a fairly high Newtonian cooling coeff. k and measuring the curve of temp. against time until the temp. had returned to that of the surroundings, so as to avoid the uncertain extrapolations inherent in measurements made with a low, but seldom low enough, value of k; the method is briefly described.
