摘　　要： Synthesis of ketals and acetals from 2,2bis(hydroxymethyl)propane1,3diol with aldehydes and ketones was catalysed by phosphotungstic acid supported on active carbon(HPW/C),and the factors influencing the yield were investigated.It is show that HPW/C was an excellent catalyst,and it was stabtilitive and reusable.The products were characterized by 1H NMR,IR and elemental analysis.
