摘要：

The adsorption of methylbenzenes on sulfated zirconia has been studied by ESR. The catalyst is shown to possess acceptor sites capable to ionize methylbenzenes. The number of acceptor sites appeared to depend on the surface sulfur concentration. Oxygen is observed to strengthen the acceptor sites.
