  • Process for separating 2-butanol from tert-butanol/water mixtures
    Publication number: 20040236159
    Abstract: The present invention relates to a process for separating 2-butanol from tert-butanol/water mixtures using a membrane to reduce a water concentration to less than the limit concentration of the distillation boundary line connecting the two azeotropes TBA/water and SBA/water and is subsequently worked up by distillation.

  • Hydroisomerisation of olefins comprising between 4 and 6 carbon atoms
    Publication number: 20040210098
    Abstract: The invention relates to a process by which C4- to C6-olefins or an essentially sulfur-free olefin cut comprising C4- to C6-olefins is isomerized over a catalyst comprising an element of the eighth transition group of the Periodic Table, in the presence of at least one added sulfur compound, and any polyunsaturated hydrocarbons contained therein are selectively hydrogenated and hydroisomerized, and also the sulfur compounds are separated from the product and optionally recycled, so that virtually sulfur-free products are obtained.

  • Process for separating 2-butanol from tert-butanol/water mixtures
    Publication number: 20040200716
    Abstract: The present invention relates to a process for separating 2-butanol from tert-butanol/water by adding of tert-butanol such that the water concentration lowers to less than the limit concentration of the distillation boundary line connecting the two azeotropes TBA/water and SBA/water and is subsequently worked up by distillation.

  • Process for removing 2-butanol from tert-butanol/water mixtures
    Publication number: 20040182691
    Abstract: The present invention relates to a process for separating secondary butanol (also referred to as 2-butanol or SBA below) from tert-butanol/water mixtures which are obtained in the dissociation of tert-butanol (TBA), in particular tert-butanol prepared from industrial C4-hydrocarbon mixtures, into isobutene and water.

  • Process for preparing tert-butanol
    Publication number: 20040171891
    Abstract: The invention relates to a process for preparing tert-butanol by reaction of a homogeneous mixture comprising water, tert-butanol and an isobutene-containing hydrocarbon mixture over an acidic ion-exchange resin at from 30 to 120° C., wherein the homogeneous mixture contains, at a proportion by mass of isobutene of above 10%, from 30 to 80% of the maximum amount of water made possible by the solubility of water in the mixture of tert-butanol and the isobutene-containing hydrocarbon mixture.

  • Method for producing a foamable plastic
    Publication number: 20040108616
    Abstract: For producing a foamable plastic, a physical blowing agent is supplied in the solid state to the plastic. Advantageously, the blowing agent is surrounded by a solid casing, which is dissolved when the plasticizing equipment is reached, the blowing agent being supplied to the plastic in the flowable and/or pourable state, especially in the form of tablets or powders. The blowing agent may also be supplied in the form of an endless material.

  • Oligomerization of isobutene in N-butenic hydrocarbon streams
    Publication number: 20040097773
    Abstract: Isobutene in isobutenic hydrocarbon mixtures is oligomerized over a solid acidic ion exchange resin, said acidic ion exchange resin containing, for example, sulfonic acid groups, some of whose protons have been exchanged for metal ions.

  • Method for producing high-purity diisobutene
    Publication number: 20040054246
    Abstract: The invention relates to a process for preparing high-purity diisobutene by reaction of isobutene or isobutene-containing hydrocarbon mixtures over a solid acidic ion-exchange resin containing sulfonic acid groups whose protons have been partly replaced by metal ions and to the use of the diisobutene.

  • Production of multilayered thin plasters comprising a carrier material based on polyurethane
    Patent number: 6616793
    Abstract: A process for producing multilayered thin plasters with a carrier material based on polyurethane with the steps of applying at least one layer of uncured polyurethane to a transfer layer, applying an adhesive composition to a release layer, laminating the uncured polyurethane on the transfer layer and the adhesive composition on the release layer together using a doctor blade, passing the laminate through nip rolls downstream of the doctor blade, and rolled out the uncured polyurethane and adhesive composition to the ultimate thickness.

  • Process for manufacturing an ornamented part
    Patent number: 6508973
    Abstract: An ink jet printhead has a number of nozzles each ejecting drops of ink toward a surface. Each nozzle has a nozzle chamber at least partially defined by an apertured roof portion operatively connected to an actuator such that the actuator moves the roof portion away from the surface to be printed to eject the ink. The ink jet printhead also has a projection within each nozzle for effectively dislodging any dried ink clogging the nozzle rim, hence preventing blocking of the nozzle.

  • Process for the cleavage of alkyl tert-alkyl ethers into isoolefins and alkanols over acid catalysts
    Publication number: 20020010379
    Abstract: Alkyl tert-alkyl ethers are cleaved into the corresponding isoolefins and alkanols by a process comprising acid-catalyzed reactive distilling an alkyl tert-alkyl ether fed into the reaction zone of a reactive distillation apparatus as an azeotrope of the alkyl tert-alkyl ether and the corresponding alkanol, wherein the reactive distillation apparatus is configured from bottom to top as a bottom zone, at least one distillation zone and a reaction zone.
