Highly efficient and chemo selective catalyst system for the synthesis of blossom orange fragrance and flavoring compounds

Acetal and acylal formation reactions of organic compounds are efficiently catalyzed by zirconia-supported mixed oxide systems under liquid-phase reaction conditions. 15WZ-750 (where, W = WO 3 and Z = ZrO 2) was the most active catalyst, which could be recyclable without loss in its activities. This...

Description
Summary:Acetal and acylal formation reactions of organic compounds are efficiently catalyzed by zirconia-supported mixed oxide systems under liquid-phase reaction conditions. 15WZ-750 (where, W = WO 3 and Z = ZrO 2) was the most active catalyst, which could be recyclable without loss in its activities. This study reports the use of a non zeolitic solid acid catalyst systems based on zirconia-supported isopoly and heteropoly acids, which are highly efficient, chemoselective, eco-friendly and cost effective catalysts for use in the condensation reactions.
