Abstract: Acetoacetic acid arylamides are continuously produced from diketene and primary or secondary aromatic amines under the conditions of a reactive distillation in the presence of water. The continuous method provides a high purity of the products, nearly quantitative yields and a high rate of throughput.

Abstract: A process for the synthesis of methanol on X-ray amorphous catalysts with a copper, zinc and zirconium oxide content in relative proportions of 10 to 70 weight percent of copper, 10 to 50 weight percent of zinc and 20 to 80 weight percent of zirconium. The process for the synthesis of methanol is distinguished by high space time yields.

Abstract: A process for preparing nicotinamide, wherein, in the first stage, 2-methyl-1,5-diaminopentane is catalytically converted into 3-picoline, then the 3-picoline is converted via an ammonoxidation into 3-cyanopyridine and, finally, the 3-cyanopyridine is converted microbiologically into the nicotinamide.

Abstract: In a process for preparing 3-methylpiperidine or 3-methylpyridine from 2-methyl-1,5-diaminopentane in the gaseous phase, the initial product is made to flow over catalysts. In the first step, 3-methylpiperidine is produced, and if required 3-methylpyridine is produced in a second step.

Abstract: Disclosed is a process for the production of gamma-butyrolactone from maleic anhydride or succinic anhydride by hydrogenation in the presence of a catalyst composition comprising the mixed oxides of copper, zinc and zirconium.

Abstract: Catalytically-active metallic glasses containing at least one element from a subgroup of the periodic system and at least one element from a main group of the periodic system. Process for the production of catalytically-active metallic glasses where the metallic glass is produced from at least one element from a subgroup of the periodic system and at least from one element from a main group of the periodic system. The metallic glasses are activated by self-activation or by an oxidative and/or reductive treatment. The catalytically-active metallic glasses can be used as hydration, oxidation or isomerization catalysts.
