Abstract

Ionic liquids (ILs) composed of tetrabutylphosphonium cations and benzoate anion derivatives with hydrophilic hydroxyl or carboxyl groups introduced onto the ortho-position were found to be less hydrophilic and showed phase separation with water, whereas unmodified benzoate-type IL was freely miscible with water.
