  • Patent number: 7709688
    Abstract: Processes comprising: (a) enantioselectively hydrogenating a staffing material comprising a component selected from geraniol, nerol and mixtures thereof to form optically active citronellol; (b) converting the optically active citronellol to optically active citronellal; (c) cyclizing the optically active citronellal to form a mixture comprising optically active isopulegol; and (d) subjecting the mixture to further processing comprising: (i) separating the optically active isopulegol from the mixture and hydrogenating the separated optically active isopulegol to form optically active menthol; or (ii) hydrogenating the optically active isopulegol in the mixture to form optically active menthol and separating the optically active menthol from the mixture.

  • Patent number: 7256312
    Abstract: The invention relates to a process for preparing 4-[aminoalkoxy]benzylamines of the general formula (I) by catalytically hydrogenating 4-[aminoalkoxy]benzonitriles of the general formula (II) where, in the compounds of the general formulae I and II, R1 is C1-C8-alkylene, R2 and R3 are each independently C1-C8-alkyl or are joined to give a ring which may additionally contain a heteroatom, which comprises carrying out the hydrogenation at elevated pressure and elevated temperatures. The invention further relates to a process for preparing the intermediate (II).

  • Publication number: 20070083066
    Abstract: The invention relates to a method for the production of 1,7 octadiene by reacting metathesis of cyclohexene with ethylene. The invention also relates to the production of 1,10-decandiol by hydroformulating 1,7 octadiene produced according to said method. The invention further relates to a method for the production of muscone or olefinically unsaturated analogs thereof using 1,10 decandiol which is obtainable in said manner.

  • Patent number: 7145042
    Abstract: The invention relates to a method for producing dialdehydes and/or ethylenically unsaturated monoaldehydes by reacting at least one compound with at least two ethylenically unsaturated double bonds with carbon monoxide and hydrogen in the presence of a hydroformylating catalyst with at least one complex of a metal of subgroup VIII. The subgroup comprises at least pnicogen chelate ligands.
