摘要：

Ethanedial, butanoic acid anhydride and trihydroxybenzenes have been determined as intermediates of resorcinol photocatalytic oxidation. The photoreaction rate shows a 1st order dependence on resorcinol concentration. The calculated reaction rate constant is 2.1x10(-8) mol dm(-3) s(-1), which is similar to the rate constant of phenol photocatalytic oxidation on TiO2 reported before.
