摘要
以活性炭负载磷钨酸为催化剂,用微波辐射法合成了5种短链季戊四醇双缩醛(3a^3 e),其中季戊四醇双缩丙醛(3b)未见文献报道。3的结构经1H NMR,IR和元素分析表征。
Five short-chain pentaerythritol diacetals(3a - 3e) were synthesized by condensation reaction of pentaerythritol with short-chain aldehydes using phosphotungstie acid supported on active carbon as the catalyst under microwave irradiation. Among 3a - 3e, diacetal of pentaerythritol with n- propylaldehyde(3b) is a new compound. The structures of 3 were characterized by ^1H NRM, IR and elemental analysis.
