Acidic and catalytic properties of alumina containing small amounts of Ti(IV) and Na(I) (up to 1 wt.% of both) were examined. It has been proved that the amount of acid sites with the strength H0 ⪬ 3.3 and the initial reaction rates of cyclohexene isomerization depend linearly on calculated total electronegativity of the corresponding mixture of oxides.
