Abstract: Pyridines are prepared by reacting a 2-alkoxy-2,3-dihydro-4H-pyran or a glutaraldehyde with ammonium nitrate in the presence of an aliphatic carboxylic acid and a catalytic amount of nitric acid. The pyridines which can be prepared by the process according to the invention are useful starting materials for the preparation of dyes, drugs and pest control agents and are useful solvents.

Abstract: Prepn. of unsatd. or satd. carbonyl cpds. of formula (I), some of which are claimed as novel cpds., is by reacting a 2-formyl-dihydropyran deriv. of formula (II) (opt. substd. by organic gps. in the 1-, 2-, 3- or 4-position) with a Gp. VIII metal (cpd.) catalyst at 100-400 deg.C to give the unsatd. cpds. and then conventionally hydrogenating the prod. should the satd. cpd. be required. In the formulae, R1 = buten-1-yl or but-1-yl opt. substd.; R2 = H or organic substit.. The cpds. claimed as novel are of formula (I) with R2 replaced by R2a where R1 is opt. substd. by R2a or R3; R2a = H or 1-20C alkyl opt. substd. by up to 3 R3 gps., but excluding unsubstd. Me or Et, where R3 = 3-12C cycloalkyl, phenyl, naphthyl, 5- or 6-membered (non)aromatic heterocycles (esp. pyridyl), 2-6C alkenyl, etc..

Abstract: Catalysts for the preparation of carboxylates from an aldehyde and an alkanol in the presence of oxygen, which contain palladium and lead as active components, these being present on a carrier containing zinc oxide, and the palladium being applied as a palladium salt in a solution containing hydrochloric acid and then being liberated by reduction, and whose carrier consists solely of zinc oxide, are particularly active and selective.

Abstract: Preparation of acetic acid, methyl acetate and/or dimethyl ether by carbonylation of anhydrous methanol or of methanol, methyl acetate and/or dimethyl ether in the presence of water at elevated temperature and pressures using cobalt-containing zeolites or undoped zeolites in the presence of cobalt salts as catalysts, the carbonylation being optionally carried out in the presence of halides as promoters.
