Process for hydrogenating aromatic compounds over a solid catalyst in the presence of a hydrogen-containing gas comprising a first reactor operated in loop mode, a second reactor operated in straight pass, at least part of the output of the first reactor is supplied to the second reactor, characterized in that the first reactor is configured as a trickle bed reactor and is operated in trickle bed mode and the second reactor is operated such that the catalyst present therein is partially flooded.

Hydrogenation of aromatic compounds

The present invention relates to a process for preparing hydroformylation products of olefins having at least four carbon atoms, in which a high proportion of both the linear C-olefins having a terminal double bond comprised in the olefin-comprising feed used and of the linear C-olefins having an internal double bond is converted into hydroformylation products. Furthermore, the invention relates to a process for preparing 2-propylheptanol which comprises such a hydroformylation process.

Method for the hydroformylation of olefins

The present invention relates to a process for the separation of at least one unbranched C4-C2O hydrocarbon from a fluid mixture containing the unbranched hydrocarbon and at least one branched isomer of the unbranched hydrocarbon, which comprises the step of&#x2014;contacting the fluid mixture with an adsorbent comprising a porous metal organic framework material, which material comprises at least one at least bidentate organic compound coordinately bound to at least one metal ion, to get the unbranched hydrocarbon adsorbed, wherein the at least one at least bidentate organic compound is a monocyclic, bicyclic or polycyclic ring system which is derived from at least one heterocycle selected from the group consisting of pyrrole, alpha-pyridone and gamma-pyridone and has at least two ring nitrogens and is unsubstituted or bears one or more substituents selected independently from the group consisting of halogen, Ci-6-alkyl, phenyl, NH2, NH(d-6-alkyl), N(C1-6-alkyl)2, OH, Ophenyl and OCi-6-alkyl, where the substituents Ci_6-alkyl and phenyl are unsubstituted or bear one or more substituents selected independently from the group consisting of halogen, NH2, NH(d-6-alkyl), N(C1-6-alkyl)2, OH, Ophenyl and OCi-6-alkyl. The present invention also relates to the use of said porous metal-organic framework material in a process for the separation of unbranched hydrocarbons from their branched isomers.

Process for the separation of unbranched hydrocarbons from their branched isomers

A process for the industrial isolation of propene from a gas stream comprising at least propene and propane, which involves contacting of the gas stream with an adsorbent having a porous metal organic framework having at least one at least bidentate organic compound coordinated to at least one metal ion, with the adsorbent becoming laden with propane and the gas stream therefore having an increased proportion of propene, wherein the W least bidentate organic compound is an imidazolate which is unsubstituted or has one or more substituents selected independently from of halogen, C-alkyl, phenyl, NH, NH(C-alkyl), N(C-alkyl), OH, O-phenyl and O&#x2014;C-alkyl.

A C4-olefin mixture having a 1,3-butadiene content of from 100 to 500 ppm and a content of 1,2-dienes of less than 10 ppm is described. The present invention further provides a process for preparing this C4-olefin mixture and provides for its use in a metathesis reaction for preparing 2-pentene and/or 3-hexene.

The invention relates to a process for preparing methylamines by gas-phase reaction of methanol and ammonia as starting materials at a pressure in the range from 15 to 30 bar in the presence of heterogeneous catalyst. The starting materials are vaporized in one or more heat exchangers (), superheated to produce a feed gas stream and subsequently fed into a reactor (), with the mixing of the starting materials being able to be carried out in the feed stream to one of the heat exchangers () or at any desired position in a heat exchanger (). A product gas stream comprising monomethylamine, dimethylamine and trimethylamine and also reaction by-products is taken off from the reactor (). To control the reactor inlet temperature of the starting materials to a temperature in the range from 360&#xb0; C. to 370&#xb0; C., all or some of the feed gas stream or the product gas stream is passed through an adjustable valve () in order to vary the pressure and thus the condensation temperature.
