In the first funding period a continuously operated miniplant for the hydroformylation of 1-dodecene was designed, built and tested. To realize an efficient catalyst recycling, a solvent-system with a highly temperature dependent miscibility gap is used. The miniplant contains a continuously stirred tank reactor (CSTR) where the homogeneous catalyzed reaction takes place and a liquid/liquid phase separator in which the product-phase and the catalyst-phase are separated from each other. After phase-separation the catalyst is fed back into the reactor and the product is taken out of the process. It was possible to realize a steady state operation of this miniplant for 200 h with a yield of 63 % of the main product.
During the following research the catalyzed recycling has to be improved further. Therefore the influence of an organic solvent nanofiltration membrane on the catalyst behavior will be investigated, to expand the miniplant with a nanofiltration-unit and increase the effectiveness of the process. Furthermore the non-polar solvent has to be separated from the product with a distillation unit and reused in the reaction-step. Also an optimal designed reactor (project B1) has to be tested in the miniplant and compared to the CSTR, in order increase the yield. Further scientific investigations on hydroformylation and hydroesterification reactions in the miniplant lead to the processing of renewable materials.
