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

摘要

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 = WO3 and Z = ZrO2) 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.
