Fundamental and applied research studies on kinetics and mechanisms of catalytic chemical reactions in solution

Ziel



The study of reactions yielding various organic compounds and polymeric materials is the target of this project. This involves investigations in the field of kinetics, mechanism and catalysis of nucleophilic addition and substitution reactions in which reagents able to form auto- and/or heteroassociates are taking part. These molecular organizations lead to specific kinetic pecularities, which result from processes evolving through different parallel routes, which, in turn, are dependent on the content variations of the reacting species in solution.

The participants are developing the concept of optimal pre-reaction complexes of microreactors lying on the reaction path, and the idea that the reaction characteristics are directly connected to the molecular structure of liquids.

In order to determine the way these microstructural factors act on the properties of such reaction systems, the study will therefore compare the kinetic behaviour of these systems in various solution media and investigate the formation of associations and complexes involving the reactive species.

One of the topics to be investigated is the reaction of isocyanates with hydroxylic compounds, including hydroxyl-terminated oligomers. The second one is the reaction of activated carbonates with amines, leading to the same urethanes while avoiding the potential hazards due to industrial handling of -NCO reagents, as well as the aminolysis of activated esters and carbamates, producing the corresponding amides and substituted ureas. This implies a search for intermediates and complexes, a study of the solvent effect and the influence of inhibitors, the use of homogeneous catalysts and the heterogeneous grafted or supported catalytic groups.
