Sixteen prepd. and corn. (mostly oxide) catalysts were tested for catalytic activity in afterburning of AcOEt to CO(2) and H(2)O in air in a flow tubular reactor. The highest combustion efficiency was obsd. when the corn. HA-100 and HA-50 catalysts as well as the prepd. V(2)O(5)(8%)/TiO(2) catalyst were used. The degree of combustion 0.9 was then achieved at 170 degrees C, 190 degrees C and 210 degrees C, resp.
