Abstract: 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,uch as reaction temperature,reaction time,concentration of TS-1 and mixing ratio of reactants.The results show that this method ischeaper,of higher selectivity and conversion and less pollution than that of conventionalmethods,In addition,we have explored the mechanism of the catalytic reaction and carriedout the quantitative analysis of products.

Key words: catechol, hydroquinone, hydroxylation of phenol, TS-1 zeolite, sythesis
