摘要
通过对硫酸盐、单质碘、SiO2负载全氟磺酸树脂、稀土固体超强酸SO24-/TiO2/La3+、铌酸、TiSiW12O40/TiO2、氯化铈等18种不同催化剂催化合成苯甲醛乙二醇缩醛实验结果的分析比较发现:稀土固体超强酸SO42-/TiO2/La3+、H4SiW12O40-PAn、多酸掺杂聚苯胺、硅钨酸、活性炭负载磷钨杂多酸、TiSiW12O40/TiO2、SiO2负载全氟磺酸树脂等催化剂催化合成苯甲醛乙二醇缩醛时收率较高,具有较高的实际应用价值。
A series of catalysts for synthesis of Benzaldehyde Glycol Aeetal were summarized. A few catalysts, such as SO4^2-/ TiO2/La^3＋ , H4SiW12O40 -PAn, TiSiW12O40/TiO2, polyoxometalate and its derivative, I2, etc. have higher productive rate than the others by analysis and eompaxison. These catalysts will be the potential catalysts in industry.
