The invention relates to a process for hydroxylating phenolic substrates such as phenols or phenol ethers. The process comprises reacting the phenolic substrate and hydrogen peroxide in the presence of a catalyst in a reaction mixture; and simultaneously removing water from the reaction mixture. The process improves the reaction rate, yield, and product selectivities.
