The present invention relates to a chemical conversion process, preferably an isomerization process, for at least one hydrocarbon in the presence of an ionic liquid. The chemical conversion is performed in a dispersion, with dispersion of the hydrocarbon (phase (B)) in the ionic liquid (phase (A)) in the dispersion, the volume ratio of phase (A) to phase (B) being in the range from 2.5 to 4:1 [vol/vol].

Chemical conversion process in a dispersion

The present invention relates to a process for separating a phase (A) from a phase (B), phase (A) having a higher viscosity than phase (B), by inverting the direction of dispersion from phase (B) in phase (A) to phase (A) in phase (B) by recycling a stream comprising phase (B) in excess.

Phase separation process by inversion of the direction of dispersion

A process for separating a phase (A) comprising at least one ionic liquid from a phase (B), where phase (A) has a higher viscosity than phase (B), comprising: a) providing a stream (S) comprising a dispersion (D) in which phase (A) is dispersed in phase (B), b) introducing stream (S) into a coalescing device (KV), where the inflow rate of stream (S) is from 0.05 to 150 kg/(cm*h) based on the average cross-sectional area of coalescing device (KV), wherein the packing density of coalescing device (KV) is from 50 to 500 kg/m, separating phase (A) from phase (B) in coalescing device (KV), discharging a stream (S) comprising at least 70% by weight of phase (A) from coalescing device (KV) and discharging a stream (S) comprising at least 70% by weight of phase (B) from coalescing device (KV).

Separation of ionic liquids in coalescing devices

The present invention relates to a process for preparing cyclohexane by isomerizing a hydrocarbon mixture (HM) comprising methylcyclopentane (MCP) in the presence of a catalyst. The catalyst is preferably an acidic ionic liquid. The starting material used is a stream (S) which originates from a steamcracking process. The hydrocarbon mixture (HM) obtained from this stream (S) in an apparatus for aromatics removal has a reduced aromatics content compared to stream (S), and (HM) may optionally also be (virtually) free of aromatics. Depending on the type and amount of the aromatics remaining in the hydrocarbon mixture (HM), especially in the case that benzene is present, the isomerization may additionally be preceded by performance of a hydrogenation of (HM). In addition, depending on the presence of other components of (HM), further purification steps may optionally be performed prior to or after the isomerization or hydrogenation. High-purity (on-spec) cyclohexane is preferably isolated from the hydrocarbon mixture (HM) obtained in the isomerization, the specifications being, for example, those applicable to the use of the cyclohexane for the preparation, known to those skilled in the art, of caprolactam.

The present invention relates to a process for separating a phase (A) comprising at least one ionic liquid from a phase (B), phase (A) having a higher viscosity than phase (B), comprising the following steps:

Removal of ionic liquids by means of a knitted fabric

In a process for the cooligomerization of olefins, an olefin starting material comprising olefins having n carbon atoms and olefins having 2n carbon atoms is reacted over an olefin oligomerization catalyst to give a reaction product. The process is carried out under such conditions that the conversion of olefins having 2n carbon atoms is less than 10%. Both the cooligomer having 3n carbon atoms and the olefin having 2n carbon atoms which has been separated off from the reaction product have a high hydroformylatability.

Process for the cooligomerization of olefins

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.

Removal of ionic liquids by means of coalescing filters made from acrylic/phenolic resin

The present invention relates to a process for preparing polyisocyanates from natural raw material sources, in which a composition comprising low molecular weight aromatics which comprise at least one hydroxy group or at least one alkoxy group per molecule (oxyaromatics) is produced from a biomass material, these oxyaromatics are converted into the corresponding aromatic amines and, optionally after condensation with formaldehyde, reacted further with phosgene to give compounds comprising isocyanate groups.

Process for preparing polyisocyanates from biomass

A method for producing membranes which contain at least one solid layer on one side of a porous substrate by treating the side of the support, which is to be coated, with a synthetic solution that forms the solid layer. The inventive method is characterized in that the space located behind the side of the porous support, which is not to be coated, is filled with an inert fluid during the production of the solid layer on the porous support, 'behind' being from the perspective of the support. The pressure and/or the temperature of the fluid is/are selected such that the synthetic solution is essentially prevented from entering in contact with the side of the porous support, which is not to be coated.

Membrane production method

The present invention relates to a process for separating at least one propylene glycol from a mixture (M) comprising water and said propylene glycol, said process comprising (I) evaporating the mixture in at least two evaporation and/or distillation stages at decreasing operating pressures of the evaporators and/or distillation columns obtaining mixture (M') and mixture (M&#x2033;); (II) separating the mixture (M&#x2032;) obtained in (I) in at least one further distillation step, obtaining a mixture (M-I) comprising at least 70 wt.-% of water and a mixture (M-II) comprising less than 30 wt.-% of water.
