Abstract
The influence of Cr2O3 on properties of the Cr2O3/MgF2 catalysts obtai ned by impregnation and precipitation-deposition is described. The IR technique enabled monitoring of changes in the structure of the MgF2 s urface after introducing chromium ions. Tetrahedral chromium complexes as well as structures of Cr2O3 type were observed. The deposited spec ies generated the Lewis and Bronsted acidity which in turn was respons ible for the catalytic activity in the reactions of 2-propanol decompo sition, butene double bond isomerization, cumene cracking, dehydrogena tion of cyclohexane and decomposition of methyl alcohol.
