Abstract
A novel reversed-phase approach is described for the separation of phenol, the cresols, the xylenols, and other methylated phenols in real samples such as shale oil. The approach, based on the fundamental optimization of mobile phase pH to provide enhanced selectivity, enables
m-cresol and
p-cresol and many xylenol isomers to be baseline resolved for the first time in a reversed-phase analysis of shale oil. Selectivities obtained with our reversed-phase method for the difficult-to-separate isomers are compared with those observed using other reversed-phase methods. The moderate oxidation potentials of the phenols allows them to be detected selectively at the unusually high (but optimum) pH of 10.82 in the presence of redox-active and redox-inactive interferents. Although unnecessary with our chromatographic method,
m-cresol and
p-cresol can also be resolved electrochemically via judicious control of the working electrode potential.
