METHOD FOR PRODUCTION OF β-PHENYL ETHYL ETHER Russian patent published in 1997 - IPC

Abstract RU 2086528 C1

FIELD: organic synthesis, perfumery. SUBSTANCE: liquid phase hydrogenation of styrene is carried out at elevated temperature and at increased pressure in the presence of alkaline agent with the help of catalyst. Supported nickel catalyst being modified by palladium and comprising ferrum is used as mentioned above catalyst. Content of nickel in said catalyst is 0.08-0.5 mass %, ratio of Ni and Pd in it being 1:(1.5-0.2) and content of ferrum is not more 0.3 mass %. It is preferably to carry out said process in the presence of water, ratio styrene oxide and water is 85:15 respectively. Selectivity of conversion styrene oxide in b-phenyl ethyl ether is up to 98 %. EFFECT: improved efficiency. 4 cl
