摘　　要：Pentaerythritol diacetals and diketals from aromatic aldehydes,aliphatic aldehydes,α,β-unsaturated aldehydes and ketones were synthesized using methanesulfonic acid as catalyst in cyclohexane under reflux temperature.The products were characterized by IR,1H NMR and elemental analysis.The procedure provided a simplified synthetic method under moderate condition in shorter reaction time,which avoids using corrosive catalyst,harmful organic solvent and water separator during the reaction.Pentaerythritol diacetals and diketals from aromatic aldehydes, aliphatic aldehydes, α, β - unsaturated aldehydes and ketones were synthesized using methanesulfonic acid as catalyst in cyclohexane under reflux temperature. The products were characterized by IR, ^1H NMR and elemental analysis. The procedure provided a simplified synthetic method under moderate condition in shorter reaction time, which avoids using corrosive catalyst, harmful organic solvent and water separator during the reaction.
