Nuclear magnetic resonance studies of interactions between cetomacrogol and phenol

Abstract

Phenol solubilized in cetomacrogol micelles appears to accumulate principally in the polyoxyethylene region and appears not to be randomly distributed along the polyoxyethylene chains. When concentrations of phenol are sufficiently high, a phenol-cetomacrogol-rich phase separates. This phase contains relatively little water and the phenol molecules may be randomly distributed along the polyoxyethylene chains. Transfer of molecules between the phases of these cloudy systems is relatively slow.
