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.
