要旨

The kinetics of the acid catalyzed reactions of acetaldehyde ammonia trimer (AAT) and paraldehyde (para) to 2-methyl-5-ethyl pyridine (MEP) in the presence of an acid catalyst were investigated systematically. A reaction model has been developed based on experimental data. With full characterisation of side products it is possible to describe the reaction as a polymerisation and to understand the different reactivity of AAT and para, respectively. A kinetic model to describe the formation of MEP and the side products was developed using operando Raman spectroscopy. The model, involving four main reactions, is able to describe the formation of MEP and side products and incorporates the effects of reactant concentration, temperature and promoter concentration. This model is an important step that allows for further process intensification and evaluation of each of the two reaction routes.

Reaction Chemistry & Engineering is an interdisciplinary journal reporting cutting-edge research focused on enhancing the understanding and efficiency of reactions. Reaction engineering leverages the interface where fundamental molecular chemistry meets chemical engineering and technology. Challenges in chemistry can be overcome by the application of new technologies, while engineers may find improved solutions for process development from the latest developments in reaction chemistry. Reaction Chemistry & Engineering is a unique forum for researchers whose interests span the broad areas of chemical engineering and chemical sciences to come together in solving problems of importance to wider society. All papers should be written to be approachable by readers across the engineering and chemical sciences. Papers that consider multiple scales, from the laboratory up to and including plant scale, are particularly encouraged.
