Вплив природи носія на ефективність B–P–W–V–Oх каталізатора синтезу акрилової кислоти альдольною конденсацією оцтової кислоти з формальдегідом

Abstract

Досліджено каталітичні системи складу B–P–W–V–Oх, нанесені на носії різної природи. Показано, що природа носія значно впливає на ефективність B–P–W–V–Oх каталізаторів. Найвищою ефективність одержання акрилової кислоти була на каталізаторі TiO2 анатаз TiO(OH)2 МХО H2O 300 rpm. За оптимальної температури 375 °С конверсія оцтової кислоти становить 63,8 %, селективність утворення акрилової кислоти – 92%, вихід акрилової кислоти – 58,8%. The catalytic systems of the B-P-W-V-Ox composition were investigated on different support types. It is shown that the nature of the support has a significant effect on the efficiency of B-P-W-V-Ox catalysts. The highest efficiency of acrylic acid production was obtained on TiO2 anatase TiO(OH)2 MchT H2O 300 rpm catalyst. At the optimal temperature 375 °С conversion of acetic acid is 63.8 %, the selectivity of acrylic acid – 92 %, the yield of acrylic acid – 58.8 %.
