摘要：
A method for hydroxylation of phenol is disclosed. The method includes the step of performing a reaction of phenol and hydrogen peroxide to form diphenol in the presence of solid catalyst with zeolite framework, wherein the solid catalyst includes silicon oxide, titanium oxide and cobalt oxide. The solid catalyst used in the preparation of diphenol of the present invention has high conversion rate of diphenol, selectivity of diphenol and higher utilization rate of hydrogen peroxide without using high concentration of hydrogen peroxide.
