Abstract
A new envirmentally-friendly catalyst,PAn-CuCl_2 was prepared.Benzaldehyde 1,2-propylene acetalization was synthesized from benzaldehyde and 1,2-propylene alcohol in the presence of polyaniline doped with copper chloride.Factors influencing the product yield were discussed and the optimum conditions were found.Experimental result showed that polyaniline doped with copper chloride is an excellent catalyst.With n(benzaldehyde)/n(1,2-propylene)=1/1.5,w(polyaniline doped with copper chloride)=0.98%,cyclohexane 14mL and reaction time 2.0 h,yield of benzaldehyde 1,2-propylene acetalization can reach 91%.
