摘要 以活性炭负载SnCl4.5H2O为催化剂,利用微波辐射法合成了8种季戊四醇双缩醛(酮),并对反应条件进行了考察。产物经过元素分析I、R和1HNMR表征。 Eight kinds of pentaerythritol diacetals and diketals Were synthesized through condensation reaction of pentaerythritol with aldehydes and ketones catalyzed by SnCl4·5H2O supported on active carbon under microwave irradiation and characterized by IR, ^1HNMB and elemental analysis. The reaction conditions were investigated . Among these products, diacetal of pentaerythritol with n-octanal is a new compound.
