METHOD OF ISOLATION OF TERT-C-C. ALKENES Russian patent published in 2000 - IPC

Abstract RU 2147019 C1

FIELD: petrochemistry. SUBSTANCE: hydrocarbon mixture is made to contact with mixture containing predominantly non- tertiary alcohol(s) having at least 2 carbon atoms and water at concentration from 0.5 to 90 wt % in the presence of highly acidic cationic catalyst. Unreacted hydrocarbons are distilled off, catalytic decomposition of the resulting compounds is carried out in the presence of highly acidic cationic catalyst, and tert-C4-C5. alkenes are distilled off. EFFECT: higher yield of the desired product and longer catalyst service life. 8 cl, 2 dwg, 2 tbl
