FIELD: catalysts. SUBSTANCE: aluminium oxide with specific surface 210-220 m2/g and mean pore radius 
is impregnated with palladium chloride solution in diluted hydrochloric acid. Mass ratio of palladium chloride to aluminium oxide is 1: 300. After impregnation the sample is dried, cooled to the room temperature and treated with 3-5% allyl alcohol solution acidified with acetic acid up to pH = 3. Catalyst is washed for alcohol excess removal and dried in the air at gradual temperature raise up to 140 C. Catalyst has 0.1-0.5% palladium. Catalyst properties: purification degree is 99.7-100%, stability is 3500 hr. EFFECT: enhanced quality of catalyst. 1 tbl
