Abstract

Anionic and cationic alkyl-chain effects on the self-aggregation of both neat and aqueous solutions of 1-alkyl-3-methylimidazolium alkylsulfonate salts ([CnH2n+ 1mim][CmH2m+ 1SO3]; n= 8, 10 or 12; m= 1 and n= 4 or 8; m= 4 or 8) have been investigated. Some of these salts constitute a novel family of pure catanionic surfactants in aqueous solution. Examples of this class of materials are rare; they are distinct from both mixed cationic–anionic ...
