Hydrotropy and Cosolvency in Lignin Solubilization With Deep Eutectic Solvents
ACS Sustainable Chemistry and Engineering, 2019 The mechanisms responsible for the good solubility of lignin in aqueous solutions of deep eutectic solvents are here investigated using both monomer model compounds and technical lignins (kraft and organosolv).

Cosolvency and Cosolvent Polarity
Pharmaceutical Research, 1987The solubilities of three poorly soluble drugs, phenytoin, benzocaine, and diazepam, in cosolvent-water mixtures have been previously shown to be approximated by the log-linear solubility equation; log (Sm/Sw) = sigma f, where Sm and Sw represent the solubilities of the drug in the solvent mixture and water, respectively, f is the volume fraction of ...

CHOOSING A COSOLVENT: SOLUBILIZATION OF NAPHTHALENE AND COSOLVENT PROPERTY
Environmental Toxicology and Chemistry, 1996Abstract The addition of an organic cosolvent to water can increase the aqueous solubility of many hydrophobic organic compounds (HOCs). This work examines the correlations between the change of naphthalene solubility and various physicochemical properties of the cosolvent added to the system.

Excluded Cosolvent in Chromatography
Journal of Pharmaceutical Sciences, 2018The concept of cosolvent exclusion was developed by a group of Timasheff's laboratory in 1970-1990 and is currently used widely to explain the effects of a variety of cosolvents on the stability and solubility of macromolecules. Not surprisingly, these concepts have had substantial influence in the fields of formulation, protein folding and unfolding ...

Understanding the Cosolvation Effect of Dendrimers
Journal of Chemical Theory and Computation, 2005Molecules that are virtually insoluble in certain solvents may be uploaded to "hostile" phases by dendrimers. Prime examples of this phenomenon are Eosin Y, EY, and Rose Bengal, RB, that are not soluble in CH2Cl2 where they can, however, be solvated through the interaction with a fourth generation dendrimer of polypropylene amine, POPAM-4D.

Polymer Bulletin, 1991
By a series of quaternization and amidoalkylation reactions, polymers based on microporous poly(styrene-co-divinylbenzene-), and containing quaternary ammonium groups (Q) and carboxamide groups (L) imitating polar aprotic solvents (DMA c and NMP) are prepared.

Die Makromolekulare Chemie, 1981
AbstractSeveral cosolvent mixtures for PMMA are reported. Their cosolvency has been confirmed by studying phase separation temperatures as a function of solvent composition. The results show that they are very powerful cosolvents. Acetonitrile forms such cosolvent mixtures with compounds containing different chemical groups (ester, ketone, alcohol ...
