Continuous miscibility from dilute solution to fused salt: volumetric properties of binary solutions of nitrobenzene, 1-butanol, and anisole with tetra-n-butylammonium picrate from 298.15 to 371.1 K

摘要

The densities and speeds of sound of binary solutions of nitrobenzene, 1-butanol, and anisole with tetra-n-butylammonium picrate have been measured over the full composition range from 298.15 to 371.1 K, in order to study the volumetric behavior of continuously miscible systems, made from an organic fused salt and a molecular organic liquid, at just above the melting point of the salt. The calculated apparent molar volumes and compressibilities are analyzed by using the equations of Petrenko and Pitzer. The thermal expansion coefficients of the above systems are also reported.
