Synthesis of iso-butyraldehyde glycol acetal by using TiSiW_(12)O_(40)/TiO_2 as catalyst

Bin Hu

Abstract

Iso butyraldehyde glycol acetal(1) was synthesized from iso butyraldehyde(2) and glycol(3) in the presence of TiSiW 12 O 40 /TiO 2(4).Factors influencing the product yield were discussed and best reaction conditions were found.Experimental result showed that 4 was an excellent catalyst.With n 3 ∶ n 2= 1.5∶1 , w 4=0.5%,and reaction time was 1.0 h,yield of 1 could reach 80.2%.
