The industrially important para-xylene oxidation reaction, based on a Co/Mn/Br catalyst, operates in a water/acetic acid (H2O/AcOH) solvent system. The correct H2O/AcOH ratio of the solvent is crucial in controlling the reaction yields and selectivit

An in-situ study of the thermal decomposition of AIBN radical chemistry using a dual mode EPR resonator

Autor: Giuseppina Magri, Michael Barter, Jack Fletcher-Charles, Heungjae Choi, Daniel Slocombe, Emma Richards, Andrea Folli, Adrian Porch, Damien M. Murphy

A custom-built dual mode EPR resonator was used to study the radical chemistry of AIBN thermal decomposition. This resonator enables both simultaneous in situ heating using microwaves and EPR measurements to be performed. The thermal decomposition of
