Catalytic Ketonization over Oxide Catalysts (Part XIV): The Ketonization and Cross-Ketonization of Anhydrides, Substituted Acids and Esters.

A series of 20 wt.% MO/S catalysts (where M = Ce, Mn or Zr and S = SiO or AlO) were prepared using various precursors of the active phases. The resulting catalysts were characterized using different methods (XRD, TPR and S).
