Abstract

NMR, UV, and IR spectroscopy were used to determine the interactions in hydrocarbon solutions between polyethylene glycol alkyl ethers, water, and aromatic hydrocarbons. The results showed a concentration dependence for the site of benzene in benzene/surfactant solutions. At low concentrations the benzene molecules were preferentially located adjacent to the surfactant oxyethylene chain with an even distribution along the chain. At high benzene concentrations a positive concentration gradient was found toward the hydrocarbon end of the oxyethylene chain. Addition of water increased this gradient except for the octa ethylene glycol dodecyl ether; for this compound the preferential water location appeared to be toward the central part of the oxyethylene chain. © 1980.
