摘要:
通过复分解法制备Dawson结构Nd2P2W18O62催化剂,并通过XRD、EDS、SEM和FT-IR等方法表征催化剂.以催化1,4-丁二醇液相脱水环化合成四氢呋喃为探针反应,通过正交实验确定了反应的最佳条件:w(催化剂)=2.6%(相对于1,4-丁二醇质量),反应温度为190 ℃,反应时间为40 min,四氢呋喃的平均产率为97.6%,催化剂重复使用到第3次时,四氢呋喃收率为87.9%.本工艺具有绿色、安全、操作简单、收率高等优点.
Abstract:
The Dawson structure heteropoly acid catalyst Nd2P2W16O62 was prepared by double decomposition method.The catalyst was characterized through XRD,EDS,SEM and FT-IR methods.Then it was used as catalyst in catalytic cyclodehydration of 1,4- butanediol to prepare tetrahyfrofuran.The optimal reaction conditions were obtained by orthogonally arranged experiments:w(catalyst)=2.6%(relative to the dosage of 1,4-butanediol),reaction temperature 190 ℃,reaction time 40 min.The average yield of THF reached 97.6%.When the catalyst being used three times,the yield of THF could reach 87.9%.This approach provides a green,safe,operation simple and highly active dehydrogenation process to produce THF.
