Catalytic synthesis of butanone glycol ketal by 12-tungstosilicic acid/polyaniline

Yang Shui-jin

Abstract

A new environmentally friendly catalyst,H 4SiW 12 O 40/PAn was prepared.Butanone glycol ketal(1) was synthesized from butanone(2) and glycol(3) in the presence of H 4SiW 12O 40/PAn(4).Factors influencing the product yield were discussed and best reaction conditions were found.Experimental result showed that 4 is an excellent catalyst.With n 2∶n 3=1.0∶1.5,w 4=0.6%,and reaction time=2.0 h,the yield of 1 could reach 70.1%.
