Oligomerisierung von 1,3-Butadien und Hydroformylierung höherer Olefine zu Oligoaldehyden

Butadiene as a bulk chemical achieves through its polymers a high industrial importance. This work describes the upscaling of an oligomerisation of 1,3-butadiene to mid size oligobutadienes from lab scale to pilot scale. A pilot plant is planned, constructed and operated based on data recieved by thermodynamic calculations and reaction calorimetrie. The influence of different reaction parameters and the workup procedure on product quality is examined after applying different product workups. Wihtin an addiational reaction step it is shown how to functionalize the previously synthesized oligobiatdienes in carbon dioxide as reaction media by hydroformylation to the corresponding oligoaldehydes. Afterwards the homogeneous catalyst system is extracted by carbon dioxide from the product. In the third part of the work a system is introduced which allows the selective hydroformylation of certain olefines out of olefin mixtures with different chain lenghts. The problem is solved by using a two phase system, where the catalyst is immobilized in a carbon dioxide phase and the liquid product are converted into the aldehydes dependent on the pressure of carbon dioxide.
