Abstract: A process for conjointly preparing methyl tert.-butyl ether and obtaining isobutene from an isobutene-containing C4-hydrocarbon mixture, wherein a) the C4-hydrocarbon mixture is reacted, in one or more etherification stages, with methanol and a primary C3 or C4-alcohol in the presence of an acid condensing agent, b) the resulting reaction mixture or mixtures are then separated into a fraction containing the unconverted hydrocarbons, the methyl tert.-butyl ether and a fraction containing the C3- or C4-alkyl tert.butyl ether and c) thereafter the C3- or C4-alkyl tert.-butyl ether is decomposed at r.. elevated temperature, in the presence of an acid catalyst, into isobutene and primary C3- or C4-alcohol.

Abstract: An improvement in the process for the manufacture of predominantly straight-chain aldehydes by hydroformylation of olefinically unsaturated compounds of 2 to 20 carbon atoms with carbon monoxide and hydrogen in which, in a first stage, aqueous cobalt solutions are treated with carbon monoxide and hydrogen at temperatures of 50 DEG to 200 DEG C and pressures of 100 to 400 atmospheres in the presence of active charcoal, zeolites or basic ion exchangers which are charged with cobalt carbonyl, in a second stage cobalt carbonyl-hydride is extracted from the reaction mixtures thus obtained, at temperatures of 20 DEG to 180 DEG C and pressures of 1 to 400 atmospheres, by means of olefinically unsaturated compounds which must be water-insoluble and liquid under the conditions used, the aqueous phase is separated off and the organic phase is transferred to a third stage and in this stage, after introducing olefinically unsaturated compounds if the latter have only been used partially for the extraction, the hydroformylation is carried out at temperatures of 70 DEG to 170 DEG C and pressures of 100 to 400 atmospheres, the improvement being that the extraction in the second stage is carried out as a co-current extraction whilst maintaining turbulent flow.

Abstract: In a continuous process for preparing amides by reaction of esters with primary or secondary amines, the reactants are introduced into a column in which there is, both above and below the point of introduction, a countercurrent flow of ascending vaporous products and descending liquid products (the amide being withdrawn from a point below the supply point), and a temperature gradient increasing from top to bottom. The esters are derived from C1- 4 acids and C1- 4 alcohols and the amines have 1-12 C atoms and may contain 1 or 2 OH groups or ether bridges; the column temperatures are not more than 260 DEG C. at the bottom and at least 20 DEG C. at the top. A part only of the top product is removed at a minimum reflux ratio of 2: 1. Exemplified products are HCONMe2, HCONHEt, HCONEt2, HCONBu2, HCONH (cyclohexyl) and AcNHEt.

Abstract: Production of saturated 3-20C alcohols by feeding a liquid stream comprising at least one 3-20C aldehyde over a hydrogenation catalyst bed in the presence of a hydrogen containing gas comprises addition of a homogeneously soluble quantity of a salt-like base containing an anion of an acid having a pKa of greater than 2. A process for the production of saturated 3-20C alcohols by feeding a liquid stream comprising at least one 3-20C aldehyde over a bed of a hydrogenation catalyst in the presence of a hydrogen containing gas comprises addition of a homogeneously soluble quantity of a salt-like base (M )n(An-) to the liquid stream where (M ) is an alkali metal ion or equivalent of an alkaline earth metal ion, (An-) is an anion of an acid having a pKa of greater than 2.

Abstract: But-2-enes are obtained from C4-hydrocarbon mixtures which contain but-1-ene and may or may not contain but-2-enes by catalytic isomerization of the but-1-ene to but-2-enes in an isomerization zone at elevated temperatures by a process in which the isomerization is carried out in combination with a distillative separation zone, the said hydrocarbon mixture being fed to the isomerization zone and/or distillative separation zone, the isomerization mixture obtained from the isomerization zone is passed into the distillative separation zone, a but-1-ene-containing fraction is removed above the lower third of the distillative separation zone and passed into the isomerization zone, and the but-2-enes or a fraction containing these are or is removed in the lower third of the distillative separation zone.

Abstract: A process for obtaining isobutene from a C4-hy-drocarbon mixture containing isobutene, which comprises (a) reacting the mixture with a primary C3- or C4-alcohol in the presence of an ion exchanger in its acid form as a condensing agent to form the corresponding C3- or C4-alkyl tert.-butyl ether by feeding the primary C3- or C4-alcohol and the C4-hydro-carbon mixture, with or without prior mixing, to an etherification reaction zone which contains the ion exchanger; (b) distilling the reaction mixture obtained from the etherification reaction zone in a first distillation zone, taking off as the top product without water washing a C4-hydrocarbon mixture comprising the unconverted hydrocarbons such top product being substantially free from isobutene and the primary C3- or C4-al-cohol and taking off as the bottom product the resulting C3or C4-alkyl tert.-butyl ether, which may contain therein primary C3- or C4-alcohol which may have been added in excess; (c) feeding the bottom product to a second reaction zone, containing an acid catalyst, in which the C3- or C4-alkyl tert.-butyl ether is decomposed at an elevated temperature to give isobutene and primary C3- and C4-alcohol; (d) feeding the mixture of isobutene and primary C3- and C4-alcohol produced in step (c) to a second distillation zone, taking off as the top product isobutene and as the bottom product the remaining C3- or C4-alcohol produced in step (c); and (e) recyoling the primary C3- or C4-alcohol which is the bottom product of step (d) to the etherification reaction zone.
