Tailored Media for Homogeneous Cellulose Chemistry: Ionic Liquid/Co-Solvent Mixtures
Co-solvents can minimize two of the major problems associated with the use of ionic liquids (ILs) as solvents for homogeneous derivatization of cellulose: high viscosity and limited miscibility with non-polar reagents or ...
Cosolvent effect of ethanol on the solubility of lutein in supercritical carbon dioxide
(Elsevier B.V., 2019)
This contribution presents new high-pressure solubility data of solid trans-lutein in pure carbon dioxide (CO2), and mixtures of CO2 and ethanol. The cosolvent effect of ethanol was determined by comparing lutein solubility ...
Comparison of yield, composition, and antioxidant activity of turmeric (Curcuma longa L.) extracts obtained using various techniques
(Amer Chemical SocWashingtonEUA, 2003)
Antioxidant and antimycobacterial activities of Tabernaemontana catharinensis extracts obtained by supercritical CO2 + cosolvent

Supramolecular aggregates of oligosaccharides with co-solvents in ternary systems for the solubilizing approach of triamcinolone
A second compound is generally associated with oligosaccharides as a strategy to maximize the solubilizing effect for nonpolar compounds. This study elucidated the role and the mechanism whereby liquid compounds interact ...
Effect of co-solvents in the enantioselective esterification of (R/S)-ibuprofen with ethanol
(Bentham Science Publishers, 2014-05)
The commercial biocatalyst Novozym 435 was used for the kinetic resolution of (R/S)-ibuprofen by esterification with short chain alcohols (ethanol, 1-propanol and 2-propanol) in the absence of organic co-solvent. The best ...
Extraction of caffeine, chlorogenic acids and lipids from green coffee beans using supercritical carbon dioxide and co-solvents
