Abstract

The catalytic systems of the B–P–W–V–Ox composition have been investigated on different types of supports. The best by the target product yield is the catalytic system of the composition B–P–W–V–Ox/TiO2 anatase. The optimal conditions for the process are: temperature – 375 °С; residence time – 8 s, at which acetic acid conversion is 63.8 %, acrylic acid selectivity – 92 % and acrylic acid yield – 58.8 %.
