M. Sc. Jonas Bianga

Amine functionalizations with integrated catalyst recycling

Curriculum Vitae:

Jonas started his bachelor studies at the TU Dortmund in 2011 and finished his bachelor thesis with the topic “Hydroformylation of 10-undecenoate in thermomorphic multicomponent systems (TMS)” at the laboratory of industrial chemistry (TC) in 2014. Within his master studies from 2014 to 2017 he absolved a six months internship in the workgroup of Prof. Dr. Bergbreiter for organic chemistry at the Texas A&M University. There he investigated phase behavior of polymer supported catalysts in Thermomorphic Multiphase Systems. In his master thesis he successfully developed a new orthogonal catalyst system for the “tandem reaction of isomerization and hydroformylation of unsaturated oleo compounds”. In 2017 he got work experience in industry through an internship at Covestro AG in Dormagen. In that he reactivated a research miniplant for the investigation and classification of different stirrer models.
 

Research Topic

Homogeneous catalysts are mostly used for research or in pharmaceutical chemistry. In the context of Sonderforschungsbereich/ Transregio 63 (SFB/ TR 63), financed by the DFG, the chances of homogeneous catalysts applications in industrial processes should be improved.

In this research the synthesis of amines with integrated catalyst recycling in thermomorphic multiphase systems should be investigated.

Possible reactions are on the one hand a two-step synthesis through a hydroformylation and a reductive amination. On the other hand both steps can be done together in a hydroaminomethylation (Figure 1). In the end of this work the both ways should be compared. In both ways the synthesis should be done in a thermomorphic multicomponent system (TMS). TMS offer a promising way for the catalyst recycle like it is shown in Figure 2.
