    Abstract: A process for preparing acrolein or acrylic acid or a mixture thereof from propane, in which the propane is initially dehydrogenated under heterogeneous catalysis to give propene, secondary components are removed and the remaining gas mixture, comprising propane and propene, is subjected to the heterogeneously catalyzed partial oxidation to acrolein or acrylic acid or a mixture thereof as the target product, target product is removed from the product gas mixture and the remaining residual gas, comprising excess oxygen and unconverted propane, is recycled into the propane dehydrogenation in such a way that the other propane fed to the dehydrogenation is at least partly converted under dehydrogenating conditions at the recycle point.

    Abstract: A process for preparing propene from propane, comprising the steps: A) a feed gas stream a comprising propane is provided; B) the fed gas stream a comprising propane, if appropriate steam and, if appropriate, an oxygenous gas stream are fed into a dehydrogenation zone and propane is subjected to a dehydrogenation to propene to obtain a product gas stream b comprising propane, propene, methane, ethane, ethene, carbon monoxide, carbon dioxide, steam, if appropriate hydrogen and, if appropriate, oxygen; C) product gas stream b is cooled, if appropriate condensed and steam is removed by condensation to obtain a steam-depleted product gas stream c; D) product gas stream c is contacted in a first absorption zone with a selective, inert absorbent which selectively absorbs propene to obtain an absorbent stream d1 laden substantially with propene and a gas stream d2 comprising propane, methane, ethane, ethene, carbon monoxide, carbon dioxide and hydrogen; E) if appropriate, the absorbent stream d1 is decompressed to a lower pressure in a first desorption zone to obtain an absorbent stream e1 laden substantially with propene and a gas stream e2 comprising propene, and gas stream e2 is recycled into the first absorption zone, F) from the absorbent stream d1 or e1 laden substantially with propene, in at least one second desorption zone, by decompression, heating and/or stripping the absorbent stream d1 or e1, a gas stream f1 comprising propene is released and the selective absorbent is recovered.

    Abstract: A process for the production of saturated aldehydes from alkanes comprises dehydrogenation of the stream to yield (n-1)C-alkenes and byproducts. The alkene undergoes hydroformylation to form the aldehyde (D). Separation of the resulting product mixture yields an aldehyde containing stream and a stream containing alkane and optionally byproducts with at least partial recycle of the alkane. A process (I) for the production of saturated nC-aldehydes from (n-1)C-alkanes comprises: (a) preparation of at least one (n-1)C-alkane stream; (b) dehydrogenation of the stream from (A) to yield a product stream comprising unreacted (n-1)C-alkane, one or more (n-1)C-alkenes and byproducts; (c) hydroformylation of the (n-1)C-alkene at least partially in the presence of the (n-1)C-alkane and optionally the byproducts in the presence of a hydroformylation catalyst with carbon monoxide and hydrogen to form the nC-aldehyde; (d) separation of the resulting product mixture to obtain a nC-aldehyde containing stream and a stream containing (n-1)C-alkane and optionally byproducts and; (e) at least partial recycle of the stream (n-1)C-alkane and optionally byproducts to step (B). Independent claims are included for: (1) a process (II) for the production of saturated 2nC-alcohols from (n-1)C-alkanes by carrying out steps (A) to (E) with aldol condensation of the nC-aldehyde in step (F) and (G) catalytic hydrogenation of the product from (F) with hydrogen to form the 2nC-alcohol; (2) an integrated process (III) for the production of saturated (2n-1)C-alcohols and 2nC-alcohols from (n-1)C-alkanes by carrying out steps (A)-(D) to yield a gas stream comprising (n-1)C-alkane and unreacted (n-1)C-alkene with aldol condensation of the 4C-aldehyde and catalytic hydrogenation to form the 2nC-alcohol; dimerization of unreacted (n-1)C-alkene in the presence of (n-1)C-alkane and byproducts using an olefin-oligomerization catalyst to form (2n-2)C-alkenes with separation and hydroformylation of the (2n-2)C-alkenes with separation and hydroformylation of the (2n-2)C-alkene to form a (2n-1)C-aldehyde and catalytic hydrogenation of aldehyde to form a (2n-1)C-alcohol and; (3) an integrated process for the production of saturated (2n-1)C-alcohols from (n-1)C-alkanes. n = 4-20.
