Abstract:
1. A process for producing a hydroxy compound comprising the following steps: (a) chlorination step: a step of producing a chlorinated hydrocarbon and hydrogen chloride from a hydrocarbon and chlorine, wherein the chlorine is supplied to the chlorination step; (b) hydrolysis step: a step of producing a hydroxy compound and hydrogen chloride from the chlorinated hydrocarbon supplied from the chlorination step and water, wherein the water is supplied to the hydrolysis step; and (c) oxidation step: a step of producing chlorine by reaction of oxygen and hydrogen chloride obtained in the chlorination step and/or the hydrolysis step, and (d) recycling at least a portion of the chlorine produced in the oxidation step (c) to the chlorination step, wherein the hydrocarbon is an aromatic compound, the chlorinated hydrocarbon is a chlorinated aromatic compound, and the hydroxyl compound is an aromatic hydroxyl compound.
