Abstract:
PROBLEM TO BE SOLVED: To provide an improved process for the preparation of an iron-doped ruthenium catalyst supported on carbon, and to provide its use for a selective liquid phase hydrogenation of a carbonyl compound to give a corresponding alcohol. SOLUTION: In the process for the preparation of the catalyst comprising iron in addition to ruthenium on the carbon support, the process comprises a stage of simultaneously precipitating the catalytically active components onto the support. The catalyst prepared can be used to obtain geraniol or nerol in good selectivity by in particular the hydrogenation of citral. COPYRIGHT: (C)2003,JPO
Abstract:
The present invention relates to a process for the alkoxylation of organic compounds comprising the reaction of at least one organic compound with at least onealkoxylating agent in the presence of a catalyst system, wherein a polyetheralcohol is obtained. The catalyst system comprises a metallo organic framework mate-rial comprising pores and at least one metal ion and at least one at least bidentate organic compound, which is coordinately bounded to said metal ion. Furthermore it relates to polyurethanes or polyurethane foams, which are obtainable by using a prepared polyether alcohol as a starting material.
