Catalytic transformations of 1-octanol and 2-ethyl-1-hexanol over oxide catalysts, part II. Promoted zinc oxide as a catalyst

Abstract

Silica supported ZnO was modified with alkaline promoters to reduce its dehydrating activity towards 1-octanol and 2-ethyl-1-hexanol. Neutralization of zinca acidic centers led to the significant decrease of the yields of alkenes formed during dehydration. Simultaneously, the enhancement of ZnO dehydrogenating activity was observed. The effect of modifier diminished in the sequence: K₂CO₃>KOH>Na₂CO₃.
