Research Abstract |
For long alkyl chain amine oxide surfactants, the specific protonation degree dependence of some solution properties has been considered to be due to hydrogen bonding between protonated and deprotonated species. In addition to this type of hydrogen bonding, we have introduced a pyridyl group or amide groups into amine oxide surfactants as new hydrogen-bonding sites. We studied the effect of the chemical structures of the surfactants on solution properties. The intermolecular or intramolecular hydrogen bond formation, the critical micelle concentration, micellar size, detergency, foaming ability, and solubilizing ability for oil-soluble dye could be controlled by the arrangement of hydrogen-bonding sites, spacer length, and alkyl chain length.
