A new highly selective catalysts for the implementation of oxidative condensation and oxidative esterification processes B–P–W–V–Ох/SiO2 on mesoporous silicon oxide with a specific surface area of 90 - 200 m2/g, size of pores 10 - 20 nm, volume of pores 0.5 - 1.0 cm3/g, which not containing micropores or mesopores of less than 8 nm in size have been developed. Se-containing catalysts for the reaction of oxidative esterification of acrolein with alcohols with the formation of acrylic acid and its esters on a microgel polymeric carrier have been developed. Determining of optimal parameters of the porous structure of solid catalysts is a simple and effective tool for increasing their efficiency and controlling the selectivity of the reactions (the ratio of the target products). The basic technological schemes for obtaining acrylic acid by condensation of acetic acid with formaldehyde, obtaining acrylic acid by oxidative condensation of methanol with acetic acid and obtaining acrylic acid by oxidation of acrolein with hydrogen peroxide in the presence of Se-catalytic microlyses have been developed. The state results have been scaled   Product Description popup.authors Vynnytska Sofiia I Voronchak Taras O Zavalii Kateryna V Kovalyk Marta P Kubitska Iryna I Lukianchuk Andrii V Milkovych Oleh I Nahorniak Mykhailo I Nebesna Yuliia V Orobchuk Oksana M Pavliuk Anastasiia S Podun Olesia R Reutskyi Volodymyr V Kharandiuk Tetiana V Khoma Khrystyna R Tsymbalista Oksana V Shevchenko Dmytro O popup.nrat_date 2020-12-07 Close
