| 摘 要： | 用 TiCl_4对脱铝丝光沸石进行同晶取代并经(NH_4)_2SO_4溶液促进,制成沸石型固体超强酸。氨吸附 TPD 和常温下正丁烷异构化反应表明,所制备的沸石型固体超强酸其酸强度和酸量大于典型的卤素系列固体超强酸 SbF_5-Al_2O_3-SiO_2。

Superacidity and Catalytic Properties of Ti-mordenite Promoted by Sulfate |
| |
| Abstract: | A zeolite type solid superacid was made from dealuminium mordenite by iso-
morphous substitution with TiCL_4 and promotion by(NH_4)_2SO_4 solution.The re-
sults of ammonia-TPD and isomerization of n-butane at room temperatures over
the solid superacid indicate that the acidity of the superacid is stronger than
that of the typical halide solid superacid S(?)F_5-Al_2O_3-SiO_2. |
