要旨

Systematic studies of acrolein oxidation and oxidative alkoxylation catalyzed by Se-modified microgel catalysts under mild reaction conditions were conducted. Se-modified microgels proved to be highly active colloidal catalysts and exhibited high performance for the oxidation of acrolein to acrylic acid and oxidative alkoxylation to the corresponding methyl/ethyl/butyl acrylates using hydrogen peroxide as a green oxidant. Methyl acrylate or acrylic acid can be synthesized in high yield (89–91%) and with high selectivity (97–99%) simply by regulating the solvent type and the concentration of selenium moieties in the microgel structure. Se-microgels exhibit exceptional catalytic activity compared with other Se-containing molecules of organic and inorganic nature. Due to the unique properties of the microgels that combine advantages from homogeneous and heterogeneous catalytic systems in terms of activity and selectivity as well as re-use possibilities, Se-microgel catalysts can be easily separated and reused in several catalytic cycles and remain highly active.

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.
