The present invention relates to an eggshell catalyst comprising an active metal selected from the group consisting of ruthenium, rhodium, palladium, platinum and mixtures thereof, applied to a support material comprising silicon dioxide, wherein the pore volume of the support material is 0.6 to 1.0 ml/g, determined by Hg porosimetry, the BET surface area is 280 to 500 m/g, and at least 90% of the pores present have a diameter of 6 to 12 nm, to a process for preparing this eggshell catalyst, to a process for hydrogenating an organic compound which comprises at least one hydrogenatable group using the eggshell catalyst, and to the use of the eggshell catalyst for hydrogenating an organic compound.

Catalyst and process for hydrogenating aromatics

A process is proposed for preparing acetylene by the Sachsse-Bartholom&#xe9; process by combustion of a natural gas/oxygen mixture in one or more burners to obtain a cracking gas which is cooled in two or more stages in burner columns, each burner having one or more burner columns assigned thereto, and said cracking gas being quenched with pyrolysis oil in the first cooling stage, to obtain a low boiler fraction comprising benzene, toluene and xylene from the one or more burner columns, which is cooled with direct cooling water and separated in a phase separator into an aqueous phase and an organic phase which comprises benzene, toluene and xylene and is fully or partly introduced to the top of the one or more burner columns as a return stream, wherein the organic phase comprising benzene, toluene and xylene from the phase separator, prior to full or partial recycling to the top of the one or more burner columns, is supplied to a selective hydrogenation over a catalyst which comprises at least one platinum group metal on an inorganic metal oxide as support, comprising 0.05 to 5% by weight of platinum group metal, based on the total weight of the catalyst, and wherein the selective hydrogenation is performed at a pressure in the range from 10 to 70 bar gauge and a temperature in the range from 0 to 100&#xb0; C.

Process for preparing acetylene by the Sachsse-Bartholom&#xe9; process

The present invention relates to a process for preparing 4-isopropylcyclohexylmethanol (IPCHM) from para-cymene. The process for preparing 4-isopropylcyclohexylmethanol (IPCHM) comprises an electrochemical process for preparing a mixture of 4-isopropylbenzaldehyde dimethyl acetal and 4-(1-alkoxy-1-methylethyl)benzaldehyde dimethyl acetal, and intermediates passed through in the process, a hydrolysis step to form the corresponding benzaldehydes and a hydrogenation of this mixture to form 4-isopropylcyclohexylmethanol (IPCHM).

Process for preparing 4-isopropylcyclohexylmethanol

The present invention relates to a process for the preparation of a composition enriched in cis-2-(2-methylprop-1-enyl)-4-methyltetrahydropyran, comprising the catalytic hydrogenation of 2-(2-methylprop-1-enyl)-4-methylenetetrahydropyran in the presence of hydrogen and a heterogeneous catalyst comprising ruthenium.

Process for the preparation of cis-rose oxide

The invention relates to a process for preparing aromatic amines by catalytically hydrogenating the corresponding aromatic nitro compound, which comprises using a copper catalyst with a support comprising SiO, the SiOhaving been prepared by wet grinding and subsequent spray drying.
