Abstract: Method for the preparation of 4-hydroxymethyltetrahydropyrans of the general formula I in which R , R , R and R denote hydrogen, C1- to C12-alkyl, C3- to C8-cycloalkyl, aryl or C7- to C20-aralkyl, by reacting tetrahydropyrancarboxylic esters of the general formula II in which R1, R2, R3 and R4 have the abovementioned meanings and R5 denotes hydrogen or C1- to C12-alkyl, at temperatures of 50 to 400 DEG C and pressures of 1 to 400 bar in the presence of hydrogen and hydrogenation catalysts.

Abstract: On-spec phthalic anhydride is prepared by distillative purification of crude phthalic anhydride by a process in which crude phthalic anhydride is fed to a distillation column which is operated at reduced pressure, the low boilers are removed at the top or in the vicinity of the top of the distillation column and the on-spec phthalic anhydride is removed from the column via a side take-off.

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.
