State of the art

During the first founding period we identified the reaction network for the hydroformylation of the long-chain olefin 1-decene, catalytic cycles with all main and side reaction were developed and mechanistic kinetic models were derived. These were reduced by subset-selection techniques and validated successfully. The second founding period was characterized by the study of solvent composition effects and the effects of variable chain length of the substrates. Thereby 1-decene, a model substrate for petro and oleo chemicals, was used to investigate the sub network of the isomerisation in detail separately and the tandem reaction consisting of isomerisation and hydroformylation (so called isomerizing hydroformylation). The results were applied for an extension of the catalytic cycle and revision of the mechanistic models, which could be validated in a broad range of temperatures and pressures, successfully. After adjusting the parameters it was also possible to apply the kinetic model to the hydroesterfication reaction.

Research goals

In the third founding period the subproject A3 deals with the experimental and kinetic research concerning the mechanism and the kinetic of the hydroaminomethylation (HAM) as tandem reaction consisting of reductive amination (RA) and hydroformylation (Hyfo). Thus, the gained knowledge and developed methods for the hydroformylation should be used to analyse and quantify the kinetics.

To require detailed knowledge regarding the overall reaction the sub-network of the reductive amination step is analysed separately in a thermomorphic solvent system. The reaction network and the catalytic cycle will be clarified for the RA to formulate and define new kinetic models. Therefore, perturbation experiments, IR spectroscopy, design of experiments and parameter reduction techniques will provide a data basis. Based on an analysis of the sub network of RA, the next step will be the direct coupling of the olefin–hydroformylation and the RA in a tandem reaction in order to formulate mechanistic kinetic models (Figure 1). Additionally, transient studies will be performed by imposed time-varying concentrations, temperatures and catalyst-ligand properties for olefins with internal double bonds. The developed kinetic models for the tandem reaction of the hydroaminomethylation should provide a basis for the design of reactors and processes. Quantitative assessment of catalyst deactivation processes through feed contamination or addition of water as well as the development of general rules for evaluation of tandem reactions (multi-pot vs. single-pot synthesis) will complete this work package.
