综述了氯化铁、硫酸铁、硫酸铁铵、SnO、硫酸铜、磺化聚氯乙烯、聚氯乙烯-三氯化铁、D61和D72离子交换树脂、维生素C、固体超强酸TiO2/SO2-4、钨硅酸、固载杂多酸盐TiSiW12O40/TiO2以及HY分子筛等13种不同催化剂催化合成丁醛1,2-丙二醇缩醛的实验结果。结果表明:硫酸铜、磺化聚氯乙烯、聚氯乙烯-三氯化铁、D61和D72离子交换树脂及TiSiW12O40/TiO2等5种催化剂对合成丁醛1,2-丙二醇缩醛的收率较高,具有实际应用价值。

The experimental results of synthesis of butyraldehyde 1,2-propanediol acetal in the presence of 13 kinds of catalysts such as FeCl 3 ·6H 2 O, Fe 2 (SO 4 ) 3 · x H 2 O, NH 4 Fe(SO 4 ) 2 , SnO, CuSO 4 , PVC-SO 3 H,polyvinyl chloride ferric chloride(PVC-FeCl 3 ), macroporous ion exchange resin, Vitamin C, solid super acid SO 2- 4 /TiO 2 , tungsten silicic acid, TiSiW 12 O 40 /TiO 2 and HY-type molecular sieve etc are reviewed. The results show that CuSO 4 , PVC-SO 3 H,polyvinyl chloride ferric chloride(PVC-FeCl 3 ), macroporous ion exchange resin, and TiSiW 12 O 40 /TiO 2 are excellent catalysts to synthesize butyraldehyde 1,2-propanediol acetal with high yield.
