Abstract:
Don’t touch! Without electrode contacts, but contact-free with microwaves in a resonant cavity the electronic conductivity of a VPO powder catalyst could be measured under the reaction conditions of the selective oxidation of n-butane to maleic anhydride. As a result, a linear correlation between conductivity and formation rate of maleic anhydride was observed.
