The catalytic hydrogenation and ammonolysis of carboxylic acids and derivatives to amines

Amines are important nitrogen-containing components with a wide range of applications, such as the synthesis of polyamides or Nylon. Today, amines are mainly produced from fossil sources. An interesting alternative method is the valorisation of biomass and residual flows for the production of such components. Therefore, in this PhD research, strategies were developed for the direct conversion of carboxylic acids and carboxamides to (primary) amines. Reactions were performed with clean reactants such as ammonia and hydrogen, and the development of green catalytic systems was key. With custom-build heterogeneous metal catalysts, high yields could be obtained for the corresponding amines. This research not only provides a clean method for the synthesis of amines, but also tackles the plastic waste pile by investigating an ammonolytic hydrogenation process for the chemolytic recycling of polyamides.
