METHOD OF FRACTION C-OLEFIN PURIFICATION Russian patent published in 1994 - IPC

Abstract RU 2021241 C1

FIELD: chemical technology. SUBSTANCE: fraction forming at the synthesis of methyl-tert.-allyl ether is purified from impurities of simple ethers and alcohols by contacting with catalyst consisting of silicon dioxide modified with aluminium oxide addition at concentration 0.1-0.15 % of silicon dioxide mass. Process is carried out at 200-250 C at the volume rate of fraction feeding 4-15 C4. Method is used for purification of 4-15h-1-olefins. EFFECT: improved method of purification. 3 cl, 1 tbl
