摘要
无溶剂微波照射下,通过硫酸氢铵催化季戊四醇和醛、酮反应合成了季戊四醇双缩醛、酮化合物.通过IR和1HNMR对产物结构进行了表征,研究了反应条件对产率的影响,最佳反应条件为微波照射功率750 W,照射时间1.5 min.
Efficient conversion of pentaerythrite with carbonyl compounds, aldehyde or ketone, to the corresponding pentaerythritol dialdehyde or diketone compounds in the presence of ammonium hydrogen sulfate under microwave irradiation without solvent was described. The structure of products was characterized by IR and ^1HNMR. The effect of reaction conditions on the yield was studied. The best reaction conditions were microwave irradiation power 750 W,microwave irradiation time 1.5 min.
