Abstract: The invention relates to a method for producing phthalic acid anhydride. In a first step, o-xylol is partially oxidized with oxygen in a reactor in the liquid phase and in the presence of an added catalyst, said oxygen being optionally mixed with an inert gas. A fraction containing unreacted xylol is distilled off from the partially oxidized mixture and returned to the first step. In a second step, the partially oxidized mixture enriched with xylol is oxidized in the gas phase to produce phthalic acid anhydride. According to the invention, toluol is separated from the fraction containing the unreacted xylol that was distilled off, preferably in the form of an azeotrope with water. By separating off the toluol, it is possible to prevent the formation of hot spots in the second step of the reaction, which improves the selectivity of the reaction overall.
