FIELD: catalysts for organic syntheses. SUBSTANCE: invention relates to activation techniques for crude catalysts used in syntheses of intermediate products for drugs and vitamins. Palladium catalyst on carbon carrier "Sibunite" is activated by ultrasound with intensity 0.1-3 W/sq.cm for 5-60 s using conical head of ultrasonic emitter which is immersed into glass with catalyst contained in sulfuric acid solution in isopropyl alcohol. EFFECT: intensified activation of catalyst. 3 dwg, 1 tbl
