Abstract: 3-(2'-Oxyethyl)dihydro-2(3H)furanones of the general formula I in which R denotes hydrogen or acetyl, are prepared by reaction of ethylene oxide with acetoacetic acid esters of the general formula II in which R denotes C1- to C4-alkyl, by carrying out the reaction in alcoholic solutions in the presence of alkali metal alkoxides at temperatures from 20 to 100 DEG C and pressures from 1 to 20 bar.

Abstract: Preparation of reduction products of 4-hydroxybutyric acid derivatives of the general formula IIa in which one of the radicals A and B denotes a methylene group and the other a cyclopropylidene group, or of C1-C4-alkyl esters (IIb) or of lactones (IIc) of these acids IIa, by catalytically hydrogenating the compounds IIa or IIb or IIc with hydrogen in the presence of a heterogeneous hydrogenation catalyst, novel compounds prepared by this process and polymers prepared therefrom.

Abstract: A process for preparing caprolactam by reacting 6-aminocapronitrile with water in the presence of catalysts comprises using a starting mixture of 6-aminocapronitrile and the tetrahydroazepine derivative of the formulaand conducting the reaction in liquid phase in the presence of a heterogeneous catalyst. Also describes a process for preparing said tetrahydroazepine derivative I and its use for preparing caprolactam and polycaprolactam.

Abstract: This invention concerns a catalyst, particularly for producing aromatic compounds with 6 to 8 atoms from non-aromatic hydrocarbons with straight-chained, branched and/or cyclic alkyl or alkylene chains, respectively, with 6 to 8 carbon atoms containing essentially at least one oxide of a transition metal of the IVB group of the periodic system and, optionally, one alkaline metal or alkaline earth metal compound and/or a compound of the third main or secondary group of the periodic system and/or a rare earth metal zinc compound or a mixture thereof, with the condition that the compounds change into the corresponding oxides upon calcination.

Abstract: A process is disclosed for preparing aliphatic alpha , omega -aminonitriles by partially hydrogenating aliphatic alpha , omega -dinitriles at an increased temperature and pressure in the presence of a solvent and a catalyst. The process is characterised in that the catalyst is obtained by thermally decomposing a metal compound selected in the group made up of metal carbonyl compounds, metal salts of C1-C6-carboxylic acids and C2-C6-dicarboxylic acids and metal complexes with diketones until the corresponding metal and/or a metal oxide thereof is obtained, provided that the metal used be nickel or cobalt.
