Preparation and Characterization of the New Nonionic Surfactants
Abstract:
A series of surfactants with double end hydrophilic groups and different chain spacers were synthesized by reacting compounds containing two end epoxy groups and different long carbon chains with poly(ethylene oxide)(PEO, Mw=400) or SPAN80. The surfactants were characterized by FTIR and 1H NMR. It was shown that the activity of the surfactant with two end hydrophilic groups and a lipophilic spacer is better than that of which has only one hydrophilic group, and the activity was increased with the length of the lipophilic spacer.
