Synthesis, characterization and surface activity of hexadecyl o-xylene sulfonate isomers

This paper deals with the synthesis of a series of hexadecyl o-xylene sulfonate isomers (with the o-xylene ring located at different positions along the n-hexadecyl chain) by a Friedel-Crafts reaction, and the Grignard reaction followed by a hydrogenation. The structure was confirmed by 1H NMR. All analytical methods indicated high levels of purities of the isomers with the orthoxylene ring located at the first, third, fifth and seventh carbon atom on the n-hexadecane chain. The critical micelle concentration (CMC), surface tension and maximum surface excess concentration at CMC and area per molecule at the interface were determined. As the o-xylene sulfonate group is shifted toward the center of the hexadecyl chain, the branching degree is enhanced and the surfactant molecule tends to produce a much looser packing at the gas-liquid interface. Accordingly, at CMC, the adsorption density decreases, the CMC increases and the tension reduction is weakened. AOCS 2009.
