  • Alkoxylations in microstructured capillary reactors
    Patent number: 7858829
    Abstract: The invention relates to a process and to an apparatus for preparing polyether alcohols by alkoxylating alcohols, and also long-chain polyether alcohols having a narrow product distribution. The process is preferably carried out continuously in the liquid phase in a microstructured reactor. An alkylene oxide or different alkylene oxides are metered at one or more points into the channels of the microreactor. The channels are cooled with the aid of a cooling medium or heated with the aid of a heating medium.
    Type: Grant

  • Process for producing metal foam and metal body produced using this process
    Patent number: 6915834
    Abstract: The invention relates to a process for producing metal foam and to a metal body produced using this process. The object is achieved by a process for producing metal foam by adding a blowing agent to a metal melt, wherein the metal melt is introduced into the die cavity of a metal die-casting machine and is foamed using a blowing agent which releases gases and is solid at room temperature.

  • Process for producing metal/metal foam composite components
    Patent number: 6874562
    Abstract: The invention relates to a process for producing metal/metal foam composite components, wherein a flat or shaped metal part is introduced into the cavity of a die, the cavity being at least partially delimited by the metal part, and then a mixture comprising a metal melt and a blowing agent which is solid at room temperature is introduced into the cavity, where it is foamed.

  • Process for producing shaped metal parts
    Patent number: 6854506
    Abstract: The invention relates to a process for producing shaped metal parts, in particular reduced-weight shaped parts made from metallic materials. In this process, a metal body with a surface which is closed on all sides and a hollow structure in the interior is placed into a die as a core and is then surrounded with a metal melt by casting. The surface region of the metal body has a mean density which is higher than the interior of the metal body by a factor of 1.5 to 20.

  • Production of large-area metallic integral foams
    Patent number: 6659162
    Abstract: The invention relates to a process for producing metal foams and to the metal bodies in foam form which are obtained in this way. The process for producing large-area integral metal foam by adding a blowing agent to a metal melt, is distinguished by the fact that the metal melt is introduced continuously into a roll nip and is brought into contact with a blowing agent which releases gases and is solid at room temperature, is formed in the roll stand and is fully foamed to form a large-area integral metal foam.

  • Method of synthesizing alkyl glucosides
    Patent number: 5646258
    Abstract: A method for synthesizing alkyl glucosides by the acetalization of sugars, particularly glucose, with alcohols in excess and subsequent separation of the excess alcohol by extraction, the extraction being carried out with an extraction agent, which is close to the critical point at a reduced pressure in the range of 0.8 to 1.3 and preferably of 0.9 to 1.2 at pressures, which are selected so that the density of the extraction agent, which is close to the critical point, is greater than 180 kg/m.sup.3.
