Abstract: A process for preparing cyclohexanol from benzene by: a) preparing cyclohexene by hydrogenating benzene in the presence of a catalyst, and b) preparing cyclohexanol by hydrating the cyclohexene in the presence of a catalyst, comprises: carrying out steps a) and b) in a reaction facility which has a bottom region at the lower end, a top region at the upper end, and a reaction zone between the top region and the bottom region which contains the catalyst according to steps a) and b), evaporating a portion of the benzene using the heat of reaction in the reaction zone, condensing it in the top region and returning it to the reaction zone, and withdrawing a reaction mixture containing cyclohexanol in the bottom region.

Abstract: Distillation apparatus, consisting of a partitioned column or a system of thermally coupled distillation columns, includes inlet lines for a hydrocarbon mixture, hydrogen and alcohol, outlet lines for low, medium and high boilers and heterogeneous hydrogenation and etherification catalysts, all located in specific segments of the apparatus. In operation hydrogen is obtained as low boiler and ether as high boiler. Distillation apparatus consists of a partitioned column or a system of thermally coupled distillation columns, including the following segments: (a) highest region of the overall arrangement; (b) concentration region of the feed unit; (c) distillation region of the feed unit; (d) upper region of the withdrawal unit; (e) lower region of the withdrawal unit; and (f) lowest region of the overall arrangement. Also provided are: a hydrocarbon mixture inlet point between segments (b) and (c); a medium boilers outlet point between (d) and (e); a low boilers outlet point in (a); a low boilers outlet point in (f); at least one hydrogen inlet point below (a); at least one alcohol inlet point in (a), (b) and/or (c); inserts containing a heterogeneous hydrogenation catalyst in (a), (d), (e) and/or (f); and inserts containing a heterogeneous etherification catalyst in (a), (b), (c) and/or (f). In operation hydrogen is obtained as low boiler and ether as high boiler. An Independent claim is included for a process for reactive distillation of hydrocarbon mixtures using the apparatus.

Abstract: Preparation of alcohol(s) comprises hydrating an alkene(s) using water and a catalyst(s) comprising a zeolite catalyst(s) of MCM-22, MCM-36, MCM-49, PSH-3 or ITQ-2 structure. An Independent claim is included for an integrated process for preparing alcohols which comprises hydrogenating an educt(s) to give an alkene(s), contacting the reaction mixture with water and a heterogeneous catalyst (comprising the above zeolitic structures) and separating unreacted educt and recycling.

Abstract: Sudstituted the abstract with a new abstract as follows: The invention relates to a continuous process for separation a mixture of hydrocarbons which has beenobtained by extractive distillation of C 4 fraction useing a selective solvent and the hydrocarbons from the fraction C 4 which are more readily soluble in the selective solvent than are the butanes and the butenes. The mixture is fed into a first distillation column in which it is separated into a steam which is taken off at the top and comprises 1,3-butadiene, propyne, possibly further low boilers and possibly water and a bottom stream comprising 1,3-butadiene, 1,2-butadiene, acetylenes and possibly further high boilers, with the proportion of 1,3-butadiene in the bottom stream from the distillatin column being regulated in such a way that it is at least sufficiently high to dilute the acetylenes to outside the range in which there is a risk of spontaneous decomposition. The stream taken off from the top of the first distillation column is fed to a second distillation column and is separated into a steam which is taken off at the top and comprises propyne, possibly further low boilers and possibly water and a bottom stream comprising pure 1,3-butadiene in the second distillation column.

Abstract: A process is proposed for obtaining a stream of aliphatic hydrocarbons comprising from 4 to 12 carbon atoms per molecule, with an increased proportion of linear alpha-olefins compared to a feed stream of aliphatic hydrocarbons comprising from 4 to 12 carbon atoms per molecule, with a content of linear alpha-olefins, linear internal olefins and dienes, wherein the feed stream is fed to a first distillation zone D 1 having at least 5 theoretical plates, in which the linear alpha-olefins are removed partly or fully as a component of a vapor stream which additionally also comprises the dienes, and at whose lower end a liquid stream is obtained which has been depleted partly or fully of linear alpha-olefins, the liquid stream from the lower end of the first distillation zone D 1 is introduced into a isomerization unit which is equipped with an isomerization catalyst over which the linear internal olefins are isomerized partly or fully to linear alpha-olefins, and the linear alpha-olefins formed in this way are removed as a component of a vapor stream ascending into the first distillation zone D 1, the vapor stream ascending out of the first distillation zone D 1 enters a selective hydrogenation unit comprising a second reactive distillation zone RD 2 in which at least a portion of the dienes are hydrogenated selectively to olefins over a low-isomerization selective hydrogenation catalyst to obtain a vapor stream which is drawn off, condensed fully or partly and drawn off as a product stream with an increased proportion of linear alpha-olefins compared to the feed stream, the distillation zone D 1 and the reactive distillation zone RD 2 being integrated in a single reactive distillation column RDK.
