WebNov 1, 2024 · However, this phenomenon takes place at larger solute concentrations. Thus, it is reasonable to expect the existence of at least a weak solvophobic interaction between TMU molecules dissolved in EG, as it was found many years ago by Craft and Wood [33] for hydrocarbon molecules in N-methylacetamide. WebMay 20, 2011 · That is, the weaker the ionic interaction is, the less ordered the arrangement of IL molecules around hydrocarbon chains, and hence, the weaker the solvophobic interaction becomes.
