    Abstract: A process for coproducing alkyl-substituted or unsubstituted THF and pyrrolidones by catalytically hydrogenating C 4 -dicarboxylic acids and/or derivatives thereof in the gas phase in the presence of copper catalysts and reacting GBL with ammonia or primary amines to give pyrrolidones comprises a) hydrogenating C 4 -dicarboxylic acids and/or derivatives thereof in the gas phase at from 200 to 300° C., from 0.1 to 100 bar, catalyst hourly space velocities of from 0.01 to 1 kg of reactant/l of catalyst*hour and reactant/hydrogen molar ratios of from 20 to 800 in the presence of catalysts comprising copper, aluminum and/or zinc to give mixtures of THF and GBL, b) separating the hydrogenation effluent obtained by distillation into a THF/water mixture as the top product and a GBL-containing bottom product, c) separating the THF/water mixture from step b) in a distillation facility consisting of three columns by withdrawing water from the bottom of the first column, recycling water-containing THF from the second into the first column, passing a side stream of the first into the second column, recycling the bottom product of the third column into the first column and withdrawing a distillate at the top of the first column, wherein a side stream of the second column is passed into the third column and the pure THF is obtained as the top product of the third column, d) recovering GBL from the GBL-containing bottom product from step b) by distillation and e) reacting the GBL obtained with ammonia or amines to give corresponding pyrrolidones.

    Abstract: A substituted indanole of formula (I) is prepared by reacting a substituted indanone of formula (II) with a base and water in the presence of a metal or metal-oxide catalyst. A substituted indanole of formula (I) is prepared by reacting, in the presence of a catalyst comprising, on a substrate, a group VIII metal or its oxide, at 10 - 100 bar pressure and 30 - 200 [deg]C, a substituted indanone of formula (II) with a base and water. The reaction is carried out in an organic solvent, wherein up to 50 weight. % water, based on the amount of solvent, is present. The base comprises 0.1 - 1.3 mole, based on 1 mole indanone of formula (II). [Image] R1> - R7>H, halogen, 1 - 20C alkyl, 6 - 14C aryl, 1 - 10C alkoxy, 2 - 10C alkenyl, 7 - 20C arylalkyl, 7 - 20C alkylaryl, 5 - 10C aryloxy, 1 - 10C fluoroalkyl, 6 - 10C haloaryl or -SiR8>3; R8>1 - 10C alkyl; and two or more of R1> - R8> may bond to form optionally substituted rings.

    Abstract: Production of a spinel monolith catalyst comprises forming or coating a molded body, especially a monolith with a surface active composition; impregnating the monolith with a solution of a compound of group 5b elements in the form of oxides or salts; and drying and optionally calcining. Production of a spinel monolith catalyst comprises forming or coating a molded body, especially a monolith with a surface active composition of formula: AxB(1-x)E2O4 (where: A = copper, half of which can be replaced by cobalt, iron, nickel manganese or chromium; B = zinc, magnesium, calcium, zirconium, cerium, tin, titanium, vanadium, molybdenum or tungsten; E = aluminum, half of which can be replaced by Fe2O3, Cr2O3, Ga2O3 or La2O3; and x = 0-0.9); impregnating the monolith with a solution of a compound of group 5b elements in the form of oxides or salts; and drying and optionally calcining.
