Abstract
The invention relates to a process for converting anthrahydroquinone dissolved in an organic solvent to hydrogen peroxide and anthraquinone by causing a mixture of oxygen and anthrahydroquinone to flow concurrently through a reaction zone. According to the invention, the mixture of oxygen and anthrahydroquinone is caused, as an almost continuous mixed dispersion, to flow through the tubular reaction zone at such a velocity that the vacuum-pipe velocity of the liquid therein is higher than 0.05 m/s. The ratio of the length of the tube used as the reactor to its diameter is at minimum approx 10, and it may contain a static mixer made up of one or several parts.
