Abstract

This paper is devoted to the prospects for the use of hyper-crosslinked polystyrene as a support for the development of catalysts for selective hydrogenation of alkynols for synthesis of fragrant substances and fat-soluble vitamins E and K. Various types of hyper-crosslinked polystyrene, characterized by different porosity, were used for the synthesis of palladium catalysts by wet-impregnation of polymers with palladium acetate. It was shown that in the case of C5 alkynol, the pore structure of the polymers does not significantly affect the observed catalytic activity, whereas for C10 and C20 alkynols, mesoporous polymers are preferable for use as supports.
