Research Topic

The profitability of an industrial scope chemical process depends, among other factors, on the availability and pricing of the chemical feedstock and the energy demand of the whole process. This can be achieved by establishing reactions based on a reliable and unproblematic feedstock such as CO2 and by combining multiple reactions into one single step. By doing so, this research aims at proving the feasibility of an alternative reaction route to an amide that itself is considered a large-scale platform chemical.

The research is carried out in close partnership with a globally renowned chemical cooperation.

The investigated reaction is the CO2 hydrogenation to formic acid in the presence of a low molecular weight amine and the consecutive condensation of the acid and the amine to an amide. The latter step is an equilibrium reaction. This study includes the investigation of the limits that the chemical equilibrium applies to the maximum yield and strategies to overcome those boundaries.

Reaktion: CO2 + Amin + H2 ->(+cat.-H2O) H-CO-NR2
