    Abstract: A reactor for testing catalyst systems which has a plurality of catalyst tubes ( 2 ) which are arranged parallel to one another in the interior space of the reactor and whose ends are welded into tube plates and also has caps ( 3 ) at each end of the reactor which each bound a cap space ( 4 ), with a fluid reaction medium ( 5 ) being fed via one cap space ( 4 ) into the catalyst tubes ( 2 ), flowing through the catalyst tubes ( 2 ) and being discharged via the other cap space ( 4 ), and is also provided with a heat exchange medium circuit in which the heat exchange medium ( 6 ) is fed in at one end of the reactor, flows through the intermediate space between the catalyst tubes ( 2 ) and flows out at the other end of the reactor, wherein the catalyst tubes ( 2 ) are arranged in two or more catalyst tube regions ( 7 ) which are thermally separate from one another, is proposed.

    Abstract: Process for the preparation of on-spec phthalic anhydride by the distillative purification of crude phthalic anhydride at reduced pressure, where the crude phthalic anhydride is passed to the distillation column above a side take-off, the low-boiling components are removed at the top of the column or in the vicinity of the top of the column and the on-spec phthalic anhydride is removed from the side take-off of the column, in which a distillation column is used whose number of theoretical plates located above the supply of the crude phthalic anhydride into the distillation column is 10 to 20 and the column is operated at a reflux ratio of from 0.1 to 0.5.
