Conclusions
-
1)
Calcium and aluminum phosphates and zirconium phosphate and dioxide catalyze the reaction of hydrogen transfer from isopropanol to methyl ethyl ketone. The activity of these catalysts in the hydrogen transfer reaction is connected with their aprotic acidity.
-
2)
The catalytic activity of tertiary calcium phosphate depends on the temperature of its preheating and passes a maximum at 500–600°.
-
3)
Catalysts of basic nature, the oxides of thorium and cerium, display significant activity in the reaction of hydrogen transfer and are not deactivated by addition of water or ethyl acetate.
