Abstract: The invention relates to a process for preparing butadiene from n-butane comprising the steps (A) providing an n-butane-containing feed gas stream, (B) feeding the n-butane-containing feed gas stream into a first dehydrogenation zone and nonoxidatively catalytically dehydrogenating n-butane to 1-butene, 2-butene and optionally butadiene to obtain a first product gas stream comprising n-butane, 1-butene and 2-butene, with or without butadiene and secondary components, (C) feeding the first product gas stream comprising n-butane, 1-butene and 2-butene, with or without butadiene and secondary components, into a second dehydrogenation zone and oxidatively dehydrogenating 1-butene and 2-butene to butadiene to give a second product gas stream comprising butadiene, n-butane and steam, with or without secondary components, (D) recovering butadiene from the second product gas stream.

Abstract: The invention relates to a method for the production of butadiene from n- butane comprising the steps: (a) preparation of a gas feedstream containing n- butane, (b) feeding the gas feedstream containing n-butane into a first dehydrogenation zone with non-oxidative catalytic dehydrogenation of n-butan e to give 1-butene, 2-butene and optionally butadiene, whereby a first gas product stream comprising n-butane, 1-butene, 2-butene, optionally butadiene and optionally by-products is obtained, (c) feeding the first gas product stream comprising n-butane, 1-butene, 2-butene, optionally butadiene and optionally by-products into a second dehydrogenation zone with oxidative dehydrogenation of 1-butene and 2- butene to give butadiene, whereby a secon d gas product stream is obtained comprising butadiene, n-butane, steam and optionally by-products and (d) recovery of butadiene from the second gas product stream.

Abstract: The invention relates to a catalyst which contains a catalytically active quantity of at least one oxygen-containing molybdenum and/or wolfram compound on an oxidic support material and which has been calcinated at temperatures of 400 to 900° C. after the precursor compound of the catalytically active compounds have been applied to the support material or to a support material precursor. The transport pores for this catalyst each have a diameter of >25 nm and a volume of at least 50 mm /g. The catalyst contains x mumol (wolfram and/or molybdenum)/m molybdenum and/or wolfram, with 10.1 /g. Catalysts of this type are characterized by an acidity of at least 70 mumol/g at pKs

Abstract: Enol ethers of the formula Iwhere R1 is an aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radical which may carry further substituents which do not react with acetylenes or allenes, and the radicals R, independently of one another, are hydrogen or aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic radicals, which may be bonded to one another to form a ring, and m is 0 or 1, are prepared by reacting an acetal or ketal of the formula IIwith an acetylene or allene of the formula III or IVwhere R and R1 have the abovementioned meanings, in the gas phase at elevated temperatures in the presence of a zinc- or cadmium- and silicon- and oxygen-containing heterogeneous catalyst.
