In addition to being used as a polymerization-control agent and stabilizer, TEMPO is also very effective as a catalyst in oxidation reactions.
Oxidation using TEMPO allows for producing reactions under very mild conditions.
We also support selective oxidation reactions. Below is a list of typical examples.
In recent years, Dr. Isogai and his team at the University of Tokyo have reported on successful nanofiberization of cellulose through oxidation with TEMPO. Because cellulose generally consists of strong hydrogen bonds between hydroxy groups in the cellulose fibers, it is difficult to uniformly break down the material. However, TEMPO oxidation allows for carboxylation of atoms of the hydroxyl groups to break them down as uniform cellulose nanofiber. This technology allows for wide applicability to the field of cellulose of materials.
