THE APPLICATIONS OF ACETAL AND KETAL IN ORGANIC SYNTHESIS

Zheng Qingyun Li Qianhuo 1 (Department of Chemistry and Chemical Engineering, Changde Teachers' University,Changde Hunan,415000) (1 Institute of Fine Catalysis and Synthesis, Hunan Normal University,Changsha Hunan,410081)  
The article summarizes the application and research development of the five kinds of solid acids such as aluminium silicate、solid super-acid、heteropolyacid、acidic cation-exchang resin、inorganic salt in catalytic synthesis of acetals or ketals.By comparison the framework silicon-to-aluminium ratio is found to proportionate to acid-side strength in the aluminium silicate and acidity is proportional with electroneg activity to radius of cation in the inorganic salt.
