The aluminosilicate LZ-135 was patented about 20 years ago. At the time, its aluminosilicate framework could not be determined. But, recently, the new framework has been assigned the framework type code LTF. The framework structure of LZ-135 is related to the framework type code LTF. For synthesis LZ-135, TMA and TEA were used as structure-directing agents. Samples of LZ-135 were synthesized with a different ratio of Si/Al(Si/Al=2.5, 5 and 10). Then, they were reacted at different temperatures and times. The results of XRD showed that the materials made by Si/Al=5 were close to LZ-135. When the ratios were 2.5 and 10, zeolite Y and sodalite were obtained respectively. |
