dc.description | Volumetric properties for the binary (ethanol + decane) and ternary (ethanol + decane + carbon dioxide) systems are reported from (313 to 363) K and pressures up to 20 MPa. Compressed liquid densities of both systems were measured in a vibrating tube densimeter at different compositions. Binary mixtures {x1 ethanol + (1-x1) decane} were prepared at x1 = 0.0937, 0.1011, 0.2507, 0.4963, 0.7526, 0.9014. Compositions for the ternary system were prepared by varying the ethanol/decane relation and trying to keep constant the presence of carbon dioxide at about 0.2 mole fraction. These were {x1 ethanol + x2 decane + (1-x1-x2) carbon dioxide} x1 = 0.0657, 0.1986, 0.4087, 0.6042, 0.7109. Density results were correlated using an empirical model with five parameters. Deviations between experimental and calculated values agree and are within the experimental uncertainty. Isobaric expansivity, isothermal compressibility, thermal pressure coefficient, and internal pressure have been calculated for both binary and ternary systems using the empirical model. | es_ES |
dc.description.abstract | Las propiedades volumétricas de los sistemas binario (etanol + decano) y ternario (etanol + decano + dióxido de carbono) se informan de (313 a 363) K y presiones de hasta 20 MPa. Las densidades de líquido comprimido de ambos sistemas se midieron en un densímetro de tubo vibratorio en diferentes composiciones. Se prepararon mezclas binarias {x1 etanol + (1-x1) decano} en x1 = 0,0937, 0,1011, 0,2507, 0,4963, 0,7526, 0,9014. Las composiciones para el sistema ternario se prepararon variando la relación etanol / decano y tratando de mantener constante la presencia de dióxido de carbono a aproximadamente 0,2 mol. Éstos eran {x1 etanol + decano + (1 x 1 x 2) dióxido de carbono x1 = 0,0657, 0,1986, 0,4087, 0,6042, 0,7109. Los resultados de densidad se correlacionaron utilizando un modelo empírico con cinco parámetros. Las desviaciones entre los valores experimentales y calculados coinciden y están dentro de la incertidumbre experimental. La expansividad isobárica, la compresibilidad isotérmica, el coeficiente de presión térmica y la presión interna se han calculado tanto para sistemas binarios como ternarios utilizando el modelo empírico. | es_ES |
