Abstract

Gas-liquid chromatography was used to determine the polarity of pure model polyoxyethylene glycol dialkyl ethers and of some their sulphur analogues. The polarity parameters were correlated with the surfactant structure and increments for characteristic groups were determined. These values can be used to estimate the polarity of surfactants using only their formulae.
