The processes of hydrogenation of phenylacetylene on a new catalyst - a hybrid material consisting of a covalent triazine framework CTF-1 (I), obtained by ampoule synthesis from 1,4-dicyanobenzene and zinc chloride at a ratio of 1:1 (wt.%) at 400° C for 40 hours, were studied followed by treatment I with copper nitrate (5% wt.) and thermal activation of the catalyst in an inert gas or hydrogen (200° C). It has been shown that during the hydrogenation of phenylacetylene under mild conditions, the conversion reaches 82%, and the selectivity for styrene exceeds 80%.
