It was shown that the dynamics of changes in the surface state of zirconium nanoparticles vs. temperature for monoclinic phase was differed from tetragonal (cubic). The catalytic activity of the obtained samples of modified zirconium dioxide was investigated in the α-pinene isomerization reaction. It was found that the isomerization of α-pinene using X ray amorphous sulfated zirconium dioxide, which was characterized by high concentrations of the acid sites and increased total specific surface area, allowed to convert 92 % α-pinene (130 °C) for 30 min in a solvent-free mixture, and obtain a camphene with a yield of 43%. The studied samples of ZrO2 can be used as selective catalysts for the functionalization of organic compounds for the needs of fine organic synthesis, production of substances for the pharmaceuticals, perfumes and flavors.
