  • Patent number: 7089620
    Abstract: A method for washing laundry and a wash path for laundry in bath change and/or counterflow operation, in which the laundry to be washed when passing through said wash path moves through different treatment zones with chambers 1 to 16, wherein the individual baths are composed of fresh water and waste water of other baths, wherein the waste water of at least one bath without intermediate storage and directly is at least partly supplied to another bath, and wherein no waste water is intermediately stored in the water circulation during washing.
    Type: Grant
    Filed: July 20, 2001
    Date of Patent: August 15, 2006
    Assignee: Senkingwerk GmbH
    Inventor: Karl-Heinz Alexander Stoll

  • Patent number: 6313323
    Abstract: A process for the gas-phase trimerization of formaldehyde to give trioxane using solid phosphoric acid catalysts. Particularly suitable catalysts for this process are SPA catalysts (solid phosphorous acid), for example “silicon phosphates”. The main advantage of this catalyst system is its simple and inexpensive production and ready availability and also, in particular, its improved long-term stability compared to the few previously described catalysts which are mostly based on supported heteropolyacids.

  • Patent number: 6191312
    Abstract: A process for preparing a bicyclooctanone, in particular 1,5-dialkylbicyclo[3.2.1]octan-8-one, by reacting a bicyclooctanol, in particular dialkylbicyclo[3.2.1]octan-8-ol, with a. a catalyst applied to an active-carbon support and comprising heteropolyoxometallate anions of vanadium, molybdenum and phosphorus, and also a corresponding alkali-metal, alkaline-earth-metal and/or ammonium counter ion, and b. a gaseous, oxygen-containing oxidizing agent.

  • Patent number: 6025524
    Abstract: The invention relates to a process for the preparation of an amine by single-stage reaction of a C.sub.2 -C.sub.20 -olefin with a compound having an NH.sub.3 group, hydrogen and carbon monoxide, wherein the reaction takes place in the presence of a catalyst, which is present in water in dissolved or suspended form, and the catalyst contains at least two metals from group VIII of the Periodic Table of the Elements in elemental or bonded form.
