PHYSICS-CHEMICAL PROPERTIES OF Au-CONTAINING CATALYTIC SYSTEMS ON THE BASE OF HYPERCROSSLINKED POLYSTYRENE
In this work physics-chemical properties of gold-containing catalytic systems synthesized by wet impregnation of polystyrene MN-270 with different precursors are shown. As metal precursors HAuCl4•4H2O and Ph3PAuCl were used. The obtained catalytic systems were used in the synthesis of 2-methyl-1,4-naphtoquinone (synthetic vitamin K3). Catalytic system 1% Au/MN-270 synthesized on the base of Ph3PAuCl showed high activity and selectivity in the studied process (75 % selectivity at 96 % conversion of 2-methylnaphtalene). Current work presents data of catalysts analysis by FTIR spectroscopy, low-temperature nitrogen physisorption, transmission electron microscopy (TEM).
