Hydroformylation of olefins has been studied in the presence of specific heterogeneous cobalt nanoparticles. The catalytic materials were prepared by pyrolysis of preformed cobalt complexes deposited onto different inorganic supports. Atomic absorption spectroscopy (AAS) measurements indicated a correlation of catalyst activity and cobalt leaching as well as a strong influence of the heterogeneous support on the productivity. These new, low-cost, easy-to-handle catalysts can substitute more toxic, unstable and volatile cobalt carbonyl complexes for hydroformylations on a laboratory scale.

Highly porous and crystalline metal-organic framework MIL-101 has been synthesized and used for the preparation of rhodium supported catalyst. Acetylacetonato(1,5-cyclooctadiene)rhodium(I) has been used as catalyst precursor. The material has been characterized by XRD, XPS, SAXS, FTIR, SEM, TEM, AAS, and nitrogen adsorption. The catalytic properties of Rh@MIL-101 have been investigated in the hydroformylation of olefins with different structure and chain length to the corresponding aldehydes. High conversion and selectivity to n-aldehydes have been achieved in the hydroformylation of n-alk-1-enes. The obtained results show that the rhodium species are highly dispersed and preferentially located at internal and less accessible sites at the supertetrahedral units.
PROCESS AND DEVICE FOR THE OXIDATION OF ORGANIC COMPOUNDS

Page/Page column 6, (2011/04/25)
The invention relates to a process for the oxidation of organic compounds by means of oxygen, in which, in a first step, the organic compound and at least part of the oxygen required for the oxidation are introduced into a first reaction zone which is operated isothermally and with backmixing and, in a second step, the reaction mixture from the first reaction zone is introduced into a second reaction zone which is operated adiabatically. The invention further relates to a reactor for carrying out the process, which comprises at least one isothermal reaction zone (3, 5) and an adiabatic reaction zone (7) which are arranged in a reactor shell (8), with each isothermal reaction zone (3, 5) being configured in the form of a jet loop reactor and the adiabatic reaction zone (7) being configured as a bubble column.
