    摘要: A process is proposed for preparing acetylene by the Sachsse-Bartholomé 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° C.

    摘要: The present invention relates to a process for hydrogenating organic nitriles by means of hydrogen in the presence of a catalyst in a reactor, where the shaped body catalyst is arranged in a fixed bed, wherein the shaped body in the shape of spheres or rods has in each case a diameter 3 mm or less, in the shape of tablets a height of 4 mm or less, and in the case of all other geometries in each case has an equivalent diameter L=1/a′ of 0.70 mm or less, where a′ is the external surface area per unit volume (mms2/mmp3), where: a ′ = A p V p , where Ap is the external surface area of the catalyst particle (mms2) and Vp is the volume of the catalyst particle (mmp3). The present invention further relates to a process for preparing downstream products of isophoronediamine (IPDA) or N,N-dimethylaminopropylamine (DMAPA) from amines prepared according to the invention.
