After an intensive study on the reactive extraction and a systematic investigation of different reactive extraction systems we developed a new alternative for this type of processes. In our studies we utlized the telomerization of butadiene and ethylene glycol as model system. Adopting the knowledge of our reaction system, we distributed the functionalities to different steps of the process and could improve the performance of the process. After theoretical work, experimental work on bench scale and simulation we managed to run long-term experiments in the mini-plant. We could approve the beneficial plant set-up and the stability of the catalyst system. The yield has been increased from 68 % to 79 % while the catalyst losses were reduced by 10 ppm palladium. The selectivity of our reaction system was stable at > 98 %.
For further investigations it should be possible to apply the developed system to other reaction systems, for example the telomerisation of butadiene with other diols, triols or sugar compounds.
