Ivasiv V. Theoretical basis of technologies of heterogeneous catalytic production of acrylate monomers

The thesis is devoted to the development of scientific basis and technology of heterogeneous catalytic production of acrylate monomers. New efficient catalysts are developed for methyl methacrylate and methacrylic acid production by reactions of condensation of propionic acid with formaldehyde, condensation of methyl propionate with formaldehyde, and combined condensation of methyl propionate and propionic acid with formaldehyde and esterification with methanol. Developed catalysts are also efficient in the processes of methyl acrylate and acrylic acid production. Dependencies between qualitative and quantitative composition of developed catalysts and their physical, chemical and catalytic properties are determined. The effect of technological parameters on the processes of synthesis of methyl methacrylate and methacrylic acid is established. The kinetic models of gas-phase condensation reactions of propionic acid and methyl propionate with formaldehyde are developed, based on which the optimization of the processes is done and the technological schemes of acrylate monomers production by condensation of carbonyl compounds in the gas phase are developed. A comparative analysis of the developed catalysts and technologies for the production of acrylate monomers with existing in industry has been performed, and pilot testing was carried out.
