    Abstract: A PROCESS IS PROPOSED FOR PARTIAL OXIDATION IN THE GAS PHASE OF C3 AND/OR C4 PRECURSOR COMPOUNDS TO (METH) ACROLEIN AND/OR (METH) ACRYLIC ACID IN THE PRESENCE OF A HETEROGENEOUS PARTICULATE CATALYST IN A REACTOR HAVING - ONE OR MORE CUBOIDAL THERMOPLATE MODULES (1) WHICH ARE EACH FORMED FROM TWO OR MORE RECTANGULAR THERMOPLATES (2) ARRANGED PARALLEL TO EACH OTHER WHILE IN EACH CASE LEAVING A GAP (3) WHICH CAN BE FILLED WITH THE HETEROGENOUS PARTICULATE CATALYST AND IS FLOWED THROUGH BY THE FLUID REACTION MIXTURE; THE HEAT OF REACTION BEING ABSORBED BY A HEAT CARRIER WHICH FLOWS THROUGH THE THERMOPLATES (2) AND THUS AT LEAST PARTLY EVAPORATING, AND ALSO HAVING- A PREDOMINANTLY CYLINDRICAL SHELL (4,15,16) WHICH RELEASES THE PRESSURE AT THE THERMOPLATE MODULES, COMPLETELY SURROUNDS THEM AND COMPRISES A CYLINDER JACKET (4) AND HOODS (15,16) WHICHS EAL IT AT BOTH ENDS AND WHOSE LONGITUDINAL AXIS IS ALIGNED PARALLEL TO THE PLANE OF THE THERMOPLATES (2), AND ALSO HAVING - ONE OR MORE SEALING ELEMENTS (7,23) WHICH ARE ARRANGED IN SUCH A WAY THAT THE FLUID REACTION MIXTURE, APART FROM FLOWING THROUGH THE REACTOR INTERIOR SPACES BOUNDED BY THE HOODS (15,16) , ONLY FLOWS THROUGH THE GAP (3).FIGURE 1

    Abstract: A process for isolating 1,4-butanediol from mixtures obtained by catalytic hydrogenation of maleic acid esters, fumaric acid esters and/or succinic acid esters, which in addition to 1,4-butanediol contain tetrahydrofuran, water, C1-C4-alcohols, succinic acid diesters, hydroxybutyric acid esters, succinic acid alkyl hydroxyalkyl esters, gamma-butyrolactone and butyric acid esters.

    Abstract: A process is claimed for the prodn of THF from mixts (I) contg THF, butane-1,4-diol (II), gamma-butyrolactone (III), succinate esters and alcohols, which are obtd by the catalytic hydrogenation of maleic, succinic or fumaric acid, or esters thereof, or maleic or succinic anhydride, in the presence of alcohols; the process comprises distn of the THF, alcohols and water, heating the residue at 100-250 deg C in the presence of a layer silicate (IV), distn of the THF and water formed in the reaction, and sepn of THF from the distillate. More specifically, (I) are produced by hydrogenation of maleic anhydride (MA) in the presence of butanols, and contain THF, butanol, propanol, (II), (III), dibutyl succinate (V) and water; distn of (I) before treatment with (IV) gives THF, propanol, butanol and water; traces of catalyst components are removed from the mixt before treatment with (IV).
