    摘要： A process for preparing higher oxo alcohols from mixtures of isomeric olefins having from 5 to 24 carbon atoms by two-stage hydroformylation in the presence of a cobalt catalyst or rhodium catalyst at elevated temperature and at elevated pressure, which comprises selectively hydrogenating the first hydroformylation stage reaction mixture, separating the hydrogenation mixture in a distillation into crude alcohol and low-boilers predominantly consisting of olefins, passing these low-boilers to the second hydroformylation stage, again selectively hydrogenating the second hydroformylation stage reaction mixture, separating the hydrogenation mixture in one distillation into crude alcohol and low-boilers, working up the crude alcohol by distillation to pure alcohol and taking off at least some of the low-boilers to discharge saturated hydrocarbons.

    摘要： Isobutene is prepared by dissociating tert-butanol into isobutene and water over an acid ion-exchange resin arranged as a fixed bed in at least one reactor at a temperature of from 80 to 150° C. and at a pressure of from 5 to 25 bar to obtain a reaction mixture, separating the reaction mixture into isobutene, a by-product, water and at least one mixture of undissociated tert-butanol and water. The reactor is operated pseudo-isothermally, with a temperature difference between inflowing and outflowing streams of less than 15 K.

    摘要： The present invention relates to a process for the preparation of 2-ethylhexanal by catalytic hydrogenation of 2-ethylhex-2-enal, wherein the hydrogenation is carried out in a plurality of two or more series-connected loops, wherein each loop involves the use of one reactor, which comprises: (a) feeding 2-ethylhex-2-enal and hydrogen to an upper part of a reactor to catalytically hydrogenate said 2-ethylhex-2-enal to produce a hydrogenation product, (b) recycling a portion of said hydrogenation product back into said upper part of said reactor, (c) feeding the remainder of said hydrogenation product from said reactor to an upper part of a subsequent reactor wherein 2-ethylhex-2-enal is catalytically hydrogenated to produce a subsequent hydrogenation product, and wherein a portion of said subsequent hydrogenation product has been recycled and is fed with said remainder of said hydrogenation product to said upper part of said subsequent reactor, (d) repeating step (c) until the subsequent reactor is the last reactor, (e) recovering the remainder of said subsequent hydrogenation product from said last reactor, and (f) obtaining 2-ethylhexanal from the product of step (e).
