Solubility enhancement in supercritical solvents
The enhancement of solubility of a solid in a supercritical solvent is interpreted with emphasis placed on binary mixtures of the second class. The selection of supercritical solvent ; the choice of temperature and pressure for supercritical fluid extractions; the characteristics of solubility curves between and in the vicinities of the upper critical and the lower critical end points; the effe...
متن کاملMultiple solubility maxima of oxolinic acid in mixed solvents and a new extension of Hildebrand solubility approach.
A new extension of the Hildebrand solubility approach which describes drug solubility in solvent mixtures showing multiple solubility peaks, the chameleonic effect, is proposed. The experimental solubilities of oxolinic acid were measured at 25 degrees C in solvent mixtures of ethanol-water and ethanol-ethyl acetate. A plot of the mole fraction of the drug against the solubility parameter (delt...
متن کاملSolubility of Thiamine in Pure and Mixed Solvents in Function of Temperature
Vitamin B1 (C12H67ClN4OS.HCl, molecular weight = 337.33 g mol–1), also called thiamine, has great importance in the food industry in general. Thiamine is a vitamin belonging to the B complex, and can be found in the cuticle of rice, brewer’s yeast, grains, egg yolk, liver, kidney, pork, fish, peanut, walnut, legumes, as well asin green and leafy vegetables. It acts in different parts of the bod...
متن کاملSolubility prediction of anthracene in mixed solvents using a minimum number of experimental data.
Numerical methods to predict the solubility of anthracene in mixed solvents have been proposed. A minimum number of 3 solubility data points in sub-binary solvents has been employed to calculate the solvent-solute interaction terms of a well established colsolvency model, i.e. the combined nearly ideal binary solvent/Redlich-Kister model. The calculated interaction terms were used to predict th...
متن کاملRapid microfluidic screening of CO2 solubility and diffusion in pure and mixed solvents.
We present a high-throughput method to determine rapidly and simultaneously the solubility and the diffusivity of CO(2) in pure solvents and mixtures using segmented flow in a microchannel. Gas bubbles are injected via a T-junction into the liquid stream and the evolution of the bubbles' lengths are followed visually. We measure both solubility and diffusion coefficient from the shrinkage and e...
