The basic kinetic regularities of aldol condensation reaction of propionic acid with formaldehyde on the B2O3-P2O5-WO3/SiO2 catalyst in gas phase have been investigated. The kinetic equations of the process have been proposed and the kinetic parameters have been calculated. The created kinetic model fairly well describes the condensation reaction of propionic acid with formaldehyde on the developed catalyst.
