| 摘 要： | 以HZSM-5为催化剂,通过大茴香醛与1,2-丙二醇反应合成了大茴香醛缩1,2-丙二醇。研究表明, HZSM-5是催化合成缩醛(酮)的理想的绿色催化剂,较优反应条件为:n(大茴香醛):n(1,2-丙二醇)=1: 1.6,w(HZSM-5)=2.5%,环己烷15 mL,回流反应2 h,反应选择性与收率均超过95%。产物通过GC、~1H NMR、IR等进行了表征。

| Abstract: | Anisic aldehyde 1,2-propylene glycol acetal was synthesized from anisic aldehyde and 1,2-propylene glycol using HZSM-5 as catalyst.The factors influencing the synthesis were studied and the optimal reaction conditions were found as follows:the molar ratio of anisic aldehyde/ethylene glycol 1/1.6,2.5%catalyst,15 mL cyclohexane and reaction time 2 h.The yield and the selectivity was above 95%and 98%,respectively.The structure of the product was identified by means of IR,GC and 1H NMR. |
