A new method for the preparation of catechol and hydroquinone by catalytic hy-droxvlation of phenol on titanium silicate(TS-1) has been reported in this paper. We have in-vestigated the influence of various parameters,such as reaction temperature,reaction time, concentration of TS-1 and mixing ratio of reactants. The results show that this method is cheaper,of higher selectivity and conversion and less pollution than that of conventional methods. In addition,we have explored the mechanism of the catalytic reaction and carried out the quantitative analysis of products.
