Using a synthetic method designed and installed with laser monitor on line, the solubility values of benzoic acid in ethanol, benzene, acetic acid and ethyl acetate were determined over the temperature range of 291.69-356.27 K. The solubility of benzoic acid in all cases investigated was found ...
The solubility of phenyl acetic acid, p-hydroxyphenylacetic acid, p-aminophenylacetic acid, p-hydroxybenzoic acid, and ibuprofen in water and in a range of organic solvents of relevance to industrial processing is reported. The solvents used are water, methanol, ethanol, 2-propanol, acetone, 4-...
Using a laser-monitoring observation technique, the solubility of hydroquinone in water, methanol, ethanol, 2-propanol, ethyl acetate, butyl acetate, and acetic acid were measured at temperatures ranging from 276.65 K to 345.10 K under the atmospheric pressure. The experimental solubility data was we...
Numerous investigators have demonstrated that solute solubility in the SCFs can be substantially improved with the addition of cosolvents (polar or non-polar)4,5,6,7,8,9,10. Gurdial et al.4, measured the solubility of o- and m-hydroxy-benzoic acid in acetone-SC-CO2and methanol-SC-CO2bina...
The solubility of MAB in binary solvent systems (viz., ethanol + water, acetonitrile + water and methanol + water) was measured between 283.15 and 323.15 K using a dynamic laser-monitoring method at atmospheric pressure. The experimental results demonstrated that the solubility of MAB increased wit...
(2) • In general, polar solutes are dissolved by polar solvents, and non-polar solutes are dissolved by non-polar solvents. • NH 4 Cl: Water = 11.1 mole% Methanol = 2.07 mole% Ethanol = 0.579 mole% n-propanol = 0.252 mole% Chloroform = 0.00 mole% Solutions (3) • Solvent-...
In addition, the polyester should itself be water-soluble or water-dispersible, either by virtue of functionalization by means of a polyalkylene oxide group and/or of a functional C1-C24end group comprising one acid group or two alcohol groups, and/or by virtue of the existence of numerous, ...
Using a synthetic method designed and installed with laser monitor on line, the solubility values of benzoic acid in ethanol, benzene, acetic acid and ethyl acetate were determined over the temperature range of 291.69-356.27 K. The solubility of benzoic acid in all cases investigated was found ...
The enhancement degree of solubility by the cosolvents is ranked with the order: ethanol>ethylene glycol>ethyl acetate. In addition, the effects of temperature, pressure and cosolvent on the solubility were also discussed. The measured data of the solubility of benzoic acid in supercritical carbon ...
The benzoic acid solubility in water alone and aqueous mixtures of the selected alcohols was in the order of; 2-propanol in water > ethanol in water > methanol in water > pure water. It is also observed that within the investigated temperature range, the acid solubility increa...
