Abstract: Furan is prepared by decarbonylation of furfural in the gas phase at elevated temperatures and under from 0.1 to 10 bar in the presence of hydrogen and a catalyst which contains platinum and/or rhodium and contains an alkali metal. The reaction is carried out in the presence of hydrogen. Catalysts which contain platinum and/or rhodium and to which cesium has been added are preferably used.

Abstract: Pyrroles are prepared by a process in which ammonia or an amine is reacted with a but-2-ene-1,4-diol in the presence of a supported catalyst containing copper, silver, zinc, palladium, nickel, cobalt and/or platinum and/or compounds of these metals as catalytic materials, and in the presence or absence of compounds of chromium and/or manganese as additional catalysts, in the gas phase. The pyrroles obtainable by the process of the invention are useful starting materials for the preparation of dyes, corrosion inhibitors, drugs and pesticides.

Abstract: 1440669 Substituted phenylindans BASF AG 16 Nov 1973 [18 Nov 1972 1 June 1973 30 May 1973] 53220/73 Heading C2C The invention comprises 1-methyl-3-(monohalogeno)-phenyl indans of the general Formula I in which R 1 , R 2 and R 3 are identical or different and each is alkyl or hydrogen and R 4 is halogen also dihalogeno-1-methyl-3-phenylindans of the general Formula II in which R 1 and R 2 are identical or different and each is alkyl or hydrogen and R 4 is a halogen substituent in the m- or p-position of the phenyl ring and in the 4-, 5- or 6-position of the indan nucleus, provided that when both radicals R 1 are methyl and one radical R 2 is hydrogen the other radical R 2 is alkyl. The compounds of Formula I may be prepared by reacting a mixture of styrene of the general Formula III and of halogenostyrene of the general Formula IV in which R 1 to R 4 have the above meanings, in the presence of phosphoric acid of at least 75% strength by weight and optionally, additionally to the acid, in the presence of an organic compound irradiated with light of 2000 to 8000 Š and capable of absorbing the said light. The compounds of Formula II in which R 1 and R 3 are identical or different and each is alkyl or hydrogen and R 4 is halogen may be obtained by reacting one or more halogeno styrenes of the general Formula IV as sole starting material(s) in the presence of phosphoric acid of at least 75% strength by weight and, additionally to the acid, in the presence of an organic compound irradiated with light of 2000 to 8000 Š and capable of absorbing the said light.

Abstract: Colloidal palladium for hydrogenating olefins, acetylene, dienes and (un)saturated nitriles consists of palladium clusters having an average particle size of 0.2-2.0 nm. At least 80% of the palladium clusters have a particle diameter which deviates not more than 0.2 nm from the average particle diameter. The clusters have protective ligands on the surface. Independent claims are also included for: (1) production of a palladium colloidal solution by reacting a palladium salt with a reductant made of 4-30 C alcohol, and a protective ligand of phosphane and/or aromatic nitrogen compound at 0-300o C; (2) production of colloidal palladium comprising forming the above palladium colloidal solution, precipitating the colloidal palladium by adding a hydrocarbon solvent, removing the colloidal palladium, and drying; and (3) production of a palladium-containing heterogeneous catalyst by forming the palladium solution as above, impregnating a carrier selected from alumina, silicon dioxide, zirconium dioxide, titanium dioxide, carbon, zeolite and silicate.
