The Supercritical Anti-Solvent precipitation (SAS) technique was invested in order to obtain the precipitation of a beta receptor drug, sotalol hydrochloride, from two different organic solvents (methanol and ethanol). In preliminary studies the solubility of sotalol hydrochloride in CO2 was determined and with the SAS batch apparatus the precipitation pressure for different drug concentration ...

The relationships between PCO2 and pH were determined in cell-free undiluted haemolymph of the arachnids Eurypelma californicum, Pandinus imperator and Cupiennius salei. The pH/bicarbonate diagrams and the CO2 equilibrium curves were calculated, using the Henderson­Hasselbalch equation, for haemolymph sampled at rest and during recovery from exercise. The calculations of solubility (alphaCO...

The solubility of CO2 in the primary, secondary, tertiary and sterically hindered amine aqueous solutions at various conditions was studied. In the present work, the Modified Kent-Eisenberg (M-KE), the Extended Debye-Hückel (E-DH) and the Pitzer models were employed to study the solubility of CO2 in amine aqueous solutions. Two explicit equations are presented to evalu...

integrally skinned asymmetric membranes based on nanocompositepolyethersulfone were prepared by the phase separation process using the supercritical co2 as a nonsolvent for the polymer solution. in present study, the effects of temperature and nanoparticle on selectivity performance and permeability of gases has beeninvestigated. it is shown that the presence of silica nanoparticles not only di...

Chemical and stable carbon isotopic modifications during the freezing of artificial seawater were measured in four 4 m tank incubations. Three of the four incubations were inoculated with a nonaxenic Antarctic diatom culture. The 18 days of freezing resulted in 25 to 27 cm thick ice sheets overlying the residual seawater. The ice phase was characterized by a decrease in temperature from 1.9 to ...

• New experimental data of the solubility CO 2 in a chemical absorption medium are reported. The Cubic Plus Association equation state with pseudo reaction approach is developed for modeling. and physical contributions to estimated predictive manner. capture plays critical role reducing carbon emissions. Novel media, such as imidazole aqueous solutions, have been extensively studied potential c...
