The influence of the support nature on physicochemical characteristics (surface acidity, porous structure) of complex oxide compositions B-P-V-W-Ox and their catalytic properties (activity, selectivity) in the reaction of gas-phase aldol condensation of acetic acid with formaldehyde to obtain acrylic acid was studied. It was found that the activity of catalysts varies symbolically with the size of the specific surface, and the selectivity of the formation of acrylic acid is determined by the presence of weak acid centers on the surface of the catalyst. In the presence of the catalyst B-P-V-W-Ox/TiO2 at a temperature of 375°C, acrylic acid was obtained with a yield of ~59% with a selectivity of formation of 92%.

载体性质对醋酸与甲醛缩合反应中BPVW-Ox氧化物组合物理化特性​​和催化性能的影响

载体性质对复合氧化物组合物BPVW-Ox的理化特性（表面酸性、多孔结构）及其催化乙酸与甲醛醛醇缩合制取丙烯酸反应的催化性能（活性、选择性）的影响被研究了。发现催化剂的活性随比表面积的大小而象征性地变化，丙烯酸形成的选择性取决于催化剂表面弱酸中心的存在。在催化剂 BPVW-Ox/TiO2 的存在下，在 375°C 的温度下，以约 59% 的产率和 92% 的形成选择性获得丙烯酸。
