OLEFIN PRODUCTION PROCESS AND CATALYST

FIELD: organic synthesis catalysts. SUBSTANCE: olefins are prepared by vapor-phase dehydration of alcohols at elevated temperature and in presence of catalyst. The latter is alumina additionally treated with aqueous solution of alkali metal acetate with metal content 0.1 to 1 M and subjected to heat...

Summary:FIELD: organic synthesis catalysts. SUBSTANCE: olefins are prepared by vapor-phase dehydration of alcohols at elevated temperature and in presence of catalyst. The latter is alumina additionally treated with aqueous solution of alkali metal acetate with metal content 0.1 to 1 M and subjected to heat treatment at 380-420 C. EFFECT: decreased amount of colored impurities and increased yield of olefin hydrocarbons. 3 cl, 3 tbl, 11 ex
