在微波辐射下, 以活性炭负载磷钨酸为催化剂, N,N-二甲基甲酰胺为溶剂, 将季戊四醇与醛(酮)缩合得到季戊四醇单缩醛(酮), 然后再与另一种醛缩合合成了9种季戊四醇杂二缩醛(酮). 产物经过元素分析, IR和1H NMR表征.

关键词: 季戊四醇, 微波辐射, 杂二缩醛, 杂二缩酮, 单缩酮, 单缩醛

Monoacetals or monoketals were synthesized by condensation reactions of pentaerythritol with aldehydes or ketone using phosphotungstic acid supported on active carbon as a catalyst and dimethylformamide as a solvent under microwave irradiation. Nine hetero diacetals and diketals of pentaerythritol were then synthesized by the condensation reactions of such monoacetals and monoketals with other aldehydes. All the mono- and heterodiacetals and ketals were characterized by elemental analysis, IR and 1H NMR spectra.

Key words: hetero diacetal, monoketal, hetero diketal, monoacetal, microwave irradiation, pentaerythritol
