The solubility of isobutane and isobutylene in associated solvents

The partition of compounds from water and from air into wet and dry ketones

“…Eqn ( 21) was used to predict the values of the 43 compound external test set, with AE = À0.090, AAE = 0.262, RMSE = 0.328 and SD = 0.332 log units. As for eqn (19) and eqn (20), the SD value for the test set predictions is quite a bit larger than PDS in eqn (21), and we think that a reasonable prediction error is 0.30 log units.…”

“…The equation for partition from the gas phase to wet MIBK is given as eqn (19). When eqn (20) was used to predict the 43 values in the external test set we found AE = À0.100, AAE = 0.280, RMSE = 0.352, SD = 0.356 log units. In this case, there are significant differences in the coefficients for the full set and for the training set, and so it is possible that the training set is not a very representative sample.…”

Vapor Liquid Equilibrium for Six Binary Systems of C4-Hydrocarbons + 2-Propanone

“…Younghun et al 1 have measured n-butane + 2-methylpropane at 330.2 K, 2-methylpropane + 2-propanone at 318.6 K, 1-butene + 2-propanone at 323.3 K, cis-2-butene + 2-propanone at 331.9 K, 2-methylpropene + 2-propanone at 323.1 K, and trans-2-butene + 2-propanone at 332.1 K. n-Butane + 2-propanone have also been previously measured 2 in temperature range of (273.2 to 313.2) K. Excess enthalpies for n-butane + 2-propene have been reported 3 at 233.15, 253.15, and 263.15 K. Solubilities of trans-2-butene in 2-propanone were found in the literature 4 at 298.15 and 323.15 K. Solubilities of 2-methylpropane and 2-methylpropene in 2-propanone have been measured 5 at 278.15, 298.15, and 318.15 K. COSMO-RS 16 has appeared as an alternative method to structure-interpolating group contribution methods (GCMs), which have been widely used by chemical engineers to predict thermophysical properties of liquid solutions for which adequate experimental data are not available. COSMO-RS is unlike GCMs able to produce the necessary information about the molecular interactions without extensive use of experimental data, which makes it more suitable for predictive purposes.…”

Analysis of thermophysical properties of binary systems containing ethyl acetate and 1-propanol or 1-butanol

“…For mixing properties, the estimated uncertainties are 6•10 -8 m 3 mol -1 for excess molar volume, 0.46 % for viscosity deviation, 8.6•10 −4 for refractive index deviation and 0.96•10 −12 Pa -1 for excess isentropic compressibility.
