New catalysts B–P–V–W–Ox/SiO2 of gas-phase condensation of acetic acid from formaldehyde to acrylic acid on an industrial carrier of stable chemical composition (colloidal silicon oxide, Aerosil A-200) were synthesized. It is shown that the hydrothermal treatment of the carrier allows to increase the activity and selectivity of the catalyst in the reactions of aldol condensation of acetic acid with formaldehyde. It was found that the developed catalyst is effective in the condensation reaction of acetic acid with formaldehyde, which allows to obtain acrylic acid with a yield of 68.7% and a selectivity of 94.1%. The kinetic regularities of the reaction on this catalyst are established. According to the proposed kinetic equations, kinetic parameters are calculated that describe the condensation reaction of acetic acid with formaldehyde.
