physico chemical and excess properties of the binary mixtures of methylcyclohexane ethanol propan 1 ol propan 2 ol butan 1 ol 2 methyl 1 propanol or 3 methyl 1 butanol at t 298 15 303 15 and 308 15 k
The Journal of Chemical Thermodynamics, 2006Co-Authors: Mrityunjaya I Aralaguppi, Jagadish G BaragiAbstract:Abstract Physico-chemical properties viz., density, viscosity, and refractive index at temperatures = (298.15, 303.15, and 308.15) K and the speed of sound at T = 298.15 K are measured for the binary mixtures of methylcyclohexane with ethanol, propan1-ol, propan-2-ol, butan-1-ol, 2-methyl-1-propanol, and 3-methyl-1-butanol over the entire range of mixture composition. From these data, excess molar volume, deviations in viscosity, molar refraction, speed of sound, and isentropic compressibility have been calculated. These results are fitted to the polynomial equation to derive the coefficients and standard errors. The experimental and calculated quantities are used to study the nature of mixing behaviours between the mixture components.

Journal of Chemical & Engineering Data, 2005Co-Authors: Andreas Heintz, Jochen K Lehmann, Christiane Wertz, Johan JacqueminAbstract:Experimental data are presented for liquid−liquid equilibria of mixtures of the room-temperature ionic liquid 1-ethyl-3-methyl-imidazolium bis(trifluoromethylsulfonyl)imide ([C2MIM][NTf2]) with the three alcohols Propan-1-Ol, butan-1-ol, and pentan-1-ol and for the 1-butyl-3-methyl-imidazolium bis(trifluoromethylsulfonyl)imide ([C4MIM][NTf2]) with cyclohexanol and 1,2-hexanediol in the temperature range of 275 K to 345 K at ambient pressure. The synthetic method has been used. Cloud points at a given composition were observed by varying the temperature and using light scattering to detect the phase splitting. In addition, the influence of small amounts of water on the demixing temperatures of binary mixtures of [C2MIM][NTf2] and Propan-1-Ol, butan-1-ol, and pentan-1-ol was investigated.

thermodynamic properties of mixtures containing ionic liquids 3 liquid liquid equilibria of binary mixtures of 1 ethyl 3 methylimidazolium bis trifluoromethylsulfonyl imide with propan 1 ol butan 1 ol and pentan 1 ol
Journal of Chemical & Engineering Data, 2003Co-Authors: Andreas Heintz, And Jochen K Lehmann, Christiane WertzAbstract:An apparatus for measuring liquid−liquid equilibria of small samples of liquid mixtures with relatively high differences in density and viscosity was applied for studying mixtures of the ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide and the three alcohols Propan-1-Ol, butan-1-ol, and pentan-1-ol. The synthetic method has been applied where cloud points at a given composition were determined by varying the temperature. The point of phase splitting was detected by light scattering. Data in the temperature range 281 K to 340 K have been obtained for the three systems.

densities and viscosities of binary mixtures of toluene with methanol ethanol propan 1 ol butan 1 ol pentan 1 ol and 2 methylpropan 2 ol at 303 15 308 15 313 15 k
Journal of Chemical & Engineering Data, 2000Co-Authors: Pandharinath S Nikam, Bapu S Jagdale, And Arun B Sawant, Mehdi HasanAbstract:Densities and viscosities of the binary mixtures of toluene with methanol, ethanol, Propan-1-Ol, butan-1-ol, pentan-1-ol, and 2-methylpropan-2-ol have been measured at 303.15, 308.15, and 313.15 K. From these data, excess molar volumes (VE) and deviations in viscosity (Δη) have been calculated. These results are fitted to Redlich−Kister type polynomial equations to estimate the binary coefficients and standard errors.

correlation and semi empirical modeling of solubility of gallic acid in different pure solvents and in binary solvent mixtures of propan 1 ol water propan 2 ol water and acetonitrile water from 293 2 to 318 2 k
Journal of Molecular Liquids, 2016Co-Authors: Imen Dali, Abdelkarim Aydi, Claumann Carlos Alberto, Zibetti Andre Wust, Abderrabba ManefAbstract:Abstract Solubility of 3,4,5-trihydroxybenzoique acid (gallic acid) in water, acetonitrile, Propan-1-Ol and propan-2-ol and in binary solvent mixtures (acetonitrile + water), (Propan-1-Ol + water) and (propan-2-ol + water) was determined at (293.15 to 318.15) K and atmospheric pressure using a thermostated reactor and UV/vis spectrophotometer analysis. The effects of variation of temperature, composition of the binary solvents mixtures and the type of the solvent in the solubility were discussed. The temperature dependence of the experimental solubility data in binary mixtures was well correlated by the modified Apelblat model. The calculated solubilities show good agreement with the experimental data in the temperature range studied which would be useful for optimizing the process of purification of gallic in industry. Using the measured solubilities data, the thermodynamic properties of dissolution of the gallic acid such as Gibbs energy ( Δ sol G° ), molar enthalpy of dissolution ( Δ sol H° ), and molar entropy of dissolution ( Δ sol S° ) were calculated.
