Abstract
A method for preparing catechol is provided. The method includes performing hydroxylation of phenol by using zirconium-containing titanium silicalite as a catalyst in the presence of phenol, a solvent and hydrogen peroxide. The method uses zirconium-containing titanium silicalite as a catalyst to increase the selectivity of phenol and utilization of hydrogen peroxide, and thus to increase the overall reaction yield.
