AbstractThe oxidation of anthracene, 9,9′‐bianthryl and 1,1,2,2‐tetraphenyl‐ 1,2‐bis (9,10‐dihydro‐anthracenyl‐9) ethane (TPDAE) by potassium chlorate and perchlorate, in the presence of vanadium pentoxide, was studied both by a batch method in closed ampoules and by gravimetry. The reactions took place with the participation of the gaseous phase while certain stages seem to be solid
