KINETICS OF ALDOL CONDENSATION OF ACETIC ACID WITH FORMALDEHYDE ON B–P–V–W–Ox/SiO2 CATALYST
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.
