  • Patent number: 7279517
    Abstract: The present invention relates to a process for the alkoxylation of organic compounds comprising the reaction of at least one organic compound with at least one alkoxylating agent in the presence of a catalyst system, wherein a polyether alcohol is obtained. The catalyst system comprises a metallo organic framework mate-rial comprising pores and at least one metal ion and at least one at least bidentate organic compound, which is coordinately bounded to said metal ion. Furthermore it relates to polyurethanes or polyurethane foams, which are obtainable by using a prepared polyether alcohol as a starting material.

  • Publication number: 20070161842
    Abstract: The invention relates to a process for preparing butadiene from n-butane having the steps of A) providing a feed gas stream a comprising n-butane; B) feeding the feed gas stream a comprising n-butane into at least one first dehydrogenation zone and nonoxidatively catalytically dehydrogenating n-butane to obtain a product gas stream b comprising n-butane, 1-butene, 2-butene, butadiene, hydrogen, low-boiling secondary constituents and in some cases steam; C) feeding the product gas stream b of the nonoxidative catalytic dehydrogenation and an oxygenous gas into at least one second dehydrogenation zone and oxidatively dehydrogenating n-butane, 1-butene and 2-butene to obtain a product gas stream c comprising n-butane, 2-butene, butadiene, low-boiling secondary constituents and steam, said product gas stream c having a higher content of butadiene than the product gas stream b; D) removing the low-boiling secondary constituents and steam to obtain a C4 product gas stream d substantially consisting of n-butane, 2-

  • Publication number: 20070055088
    Abstract: A) Provision of an n-butane-containing feed gas stream a; B) introduction of the n-butane-containing feed gas stream a into at least one dehydrogenation zone and nonoxidative catalytic dehydrogenation of n-butane to give a product gas stream b comprising n-butane, 1-butene, 2-butene, butadiene, hydrogen, low-boiling secondary constituents and possibly water vapor; C) removal of hydrogen, the low-boiling secondary constituents and, if appropriate, water vapor to give a C4 product gas stream c consisting essentially of n-butane, 1-butene, 2-butene and butadiene; D) separation of the C4 product gas stream c into a recycle stream d1 consisting essentially of n-butane and a stream d2 comprising 1-butene, 2-butene and butadiene by extractive distillation and recirculation of the recycle stream d1 consisting essentially of n-butane to the dehydrogenation zone; E) introduction of the stream d2 comprising 1-butene, 2-butene and butadiene into a selective hydrogenation zone and selective hydrogenation of butadiene to

  • Publication number: 20060293549
    Abstract: A process for preparing a C4- to C12-olefin (olefin A) from another C4- to C12-olefin (olefin B), wherein olefin (A) and olefin (B) differ with regard to the position of the double bond, and wherein a gaseous mixture comprising olefin (B) and from 0.01 to 10% by weight, based on the total amount of hydrocarbon compounds in this mixture, of a compound having a dipole moment of from 0.5 to 5 debye (compound P) is contacted with a basic catalyst at a temperature of from 200 to 700° C.

  • Publication number: 20050016830
    Abstract: A column is described for carrying out reactive distillations in the presence of a heterogeneous particulate catalyst having an ordered packing or random packings which form intermediate spaces in the column interior, the quotient of the hydraulic diameter for the gas flow through the ordered packing or the random packings and the equivalent diameter of the catalyst particles being in the range from 2 to 20, preferably in the range from 5 to 10, in such a manner that the catalyst particles are introduced into the intermediate spaces, distributed and discharged loose under the action of gravity.
