FIELD: chemical industry. SUBSTANCE: proposed supported catalyst contains 1.5-2.5 mass % of palladium, carbon being used as carrier. Said palladium is concentrated in active layer having thickness 10-50 μm, particles of palladium with preliminary size 2-8 nm are displaced in pores of said carrier having size 3-15 nm. Proposed catalyst is prepared by applying palladium on granulated carrier, aqueous solution of palladium nitrate being used. Said solution contains free nitric acid, its quantity being 6:1-1:1 as calculated for palladium. Then drying at 110-130 C in air stream is carried out. Decomposition of thus applied palladium nitrate is carried out at 200-300 C in stream of inert gas, its reduction takes place at 150-250 C in hydrogen. EFFECT: improves quality of desired product. 3 cl, 1 dwg, 1 tbl
