Gas-phase contact oxidation of various organic compounds was carried out us
ing an iron phosphate catalyst with a P/Fe atomic ratio of 1.2. The obtaine
d selectivities were compared with those obtained with catalysts consisting
of vanadium phosphate or molybdenum phosphate. The characteristics of iron
phosphate as a selective oxidation catalyst were elucidated. (C) 1999 Else
