Pressure−composition diagrams were measured at different temperatures ranging from 293.15 to 353.15 K for perfluoroalkanes including linear (perfluoro-n-octane), cyclic (perfluorodecalin and perfluoromethylcyclohexane), aromatic compounds (perfluorobenzene perfluorotoluene), pressures up 100 bar. Measurements performed using a high-pressure cell with sapphire window that allows direct observation of the phase transition. The molecular structures chosen in order check influence nature solvent...
The aim of this work is to establish a comparison between the solubility hydrochloride and non-hydrochloride forms ciprofloxacin tetracycline in relevant solvents. For that purpose solubilities were measured water, ethanol, 2-propanol, acetone, temperature range 293.15 323.15 K for 288.15 303.15 tetracycline. obtained results compared with those part I study, published previously, where respective antibiotics same solvents investigated. water about 2 orders magnitude higher than base forms....
There is a current interest in the development of new stimuli-responsive materials using biodegradable and biocompatible molecules, mainly if biomedical applications are envisaged. In this work, chitosan (a cationic polyelectrolyte obtained from renewable resources) two ammonium-based ionic liquids (ILs), namely, choline chloride ([Ch][Cl]) dihydrogen phosphate ([Ch][DHP]), were used to develop that can be as improved electrical pH-sensitive drug delivery systems. The influence each IL...
The solubility of oxygen in n-hexane and n-perfluorohexane was determined experimentally calculated by computer simulation. A precision apparatus based on a saturation method at constant pressure used to measure the temperatures from 288 313 K close atmospheric pressure. Henry's law coefficients, H2,1(T,psat1), were obtained experimental data their temperature dependence represented appropriate correlations. results characterised average deviations H2,1 these smoothing equations is ±0.5%...
A molecular model within a SAFT context for quantitatively predicting the solubility of xenon and oxygen in n-perfluoroalkanes is presented discussed here. All species are treated as Lennard-Jones chains formed by tangentially bonded spheres with same diameter dispersive energy. Optimized meaningful values both parameters pure perfluoroalkanes also used to accurately predict vapor−liquid liquid−liquid equilibria n-alkane + n-perfluoroalkane mixtures. Because high nonideality mixtures,...
