Abstract:Extraction is a common
approach to separating aromatics and alkanes, but solvent recovery
remains an issue. The polarity, hydrophobic/hydrophilic balance, and
other properties of switchable solvents can be reversibly changed
in the presence of various triggers, and taking advantage of this
property can greatly simplify the process of solvent recovery. In
this work, quaternation and anion exchange were used to prepare several
switchable solvents by introducing OH– ions to derivatives
of the amidine compound 1,8… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
