  • Selective hydrogenation of olefinically unsaturated carbonyl compounds
    Patent number: 6916964
    Abstract: The present invention relates to a continuous process for the selective hydrogenation of olefinically unsaturated carbonyl compounds to give unsaturated alcohols in particular of citral to give a mixture of geraniol and nerol, in a reactor containing a liquid phase, in which at least one catalyst is suspended, and which can additionally contain a gas phase, wherein the liquid phase and, if present, the gas phase are passed through a device in the reactor having openings or channels.
    Type: Grant

    Assignee: BASF AG
    Inventors: Hans-Georg Göbbel, Till Gerlach, Frank Funke, Klaus Ebel, Signe Unverricht, Gerd Kaibel
  • Catalyst for epoxidation reactions
    Patent number: 6884743
    Abstract: The present invention relates to the manufacture of solid materials or shaped bodies containing at least one zeolite and being at least partly crystalline. Furthermore, the present invention relates to the solid materials or shaped bodies as such and to the use of these materials for reactions of compounds having at least one C—C double bond with at least one hydroperoxide. Specifically, the present invention relates to a process for the manufacture of a solid material containing at least one zeolite and being at least partly crystalline, wherein the synthesis of the said solid material involves at least one partial step of contacting at least one transition metal oxide source with at least one epoxide or hydrolysate thereof prior to or during the at least partial crystallization of said solid material.
