Autor: Roman Nebesnyi, N. S. Pavliuk, Volodymyr Ivasiv, Oksana Orobchuk, D. S. Shevchenko
Publikováno v: Chemistry, Technology and Application of Substances. 3:39-45
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 h
