The ZnO/MgO-SiO2 catalyst with MgO:SiO2=1:1 is higher active/selective for 1,3-butadiene in the conversion of ethanol-water mixture among the studied ZnO (Cu)/MgO-SiO2 catalysts due to the optimal ratio of acid-basic surface sites. The most productive (above 0.4 g1.3-DB · gcat-1 · h-1) are compositions prepared by wet mixing of ZnO and ZrO2-SiO2 nanoparticles, followed by heat treatment. The possibility of obtaining low molecular weight oligodienes with terminal hydroxyl groups by the radical polymerization of the C4 fraction with the addition of activators that can form hydroperoxides has been investigated. The formed hydroperoxides decompose to form hydroxyl and hydroxyl-containing radicals, which leads to the production of bifunctional oligomers. The content of hydroxyl groups in oligomers for which acceptable yields are reached is 0.60-3.77%. Product Description popup.authors Kyriienko Pavlo I. Larina Olga V. popup.nrat_date 2020-04-02 Close
