TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Properties: The MCM-22 family molecular sieve has a peak between 26.6 and 29degrees (2theta) with a two theta (2theta) value of 26.9degrees, a platelet morphology having a crystal thickness at least 300 Angstrom measured by SEM, an external surface area less than 110 (preferably less than 85) m2/g measured by Brunauer Emmett Teller (BET), and a mesitylene uptake of less than 29 (preferably less than 25) mg/g measured at 0.266 kpa-a (2 torr) mesitylene partial pressure and 100degreesC. The MCM-22 family molecular sieve has an X-ray diffraction pattern including one or more of 10 values, e.g. 13.53plus minus 0.2 Angstrom (interplanar d-spacing) and M-VS (relative intensity). The X-ray diffraction pattern of calcined MCM-22 family molecular sieve includes values, e.g. 30.0plus minus 2.2 Angstrom (interplanar d-spacing) and W-M (relative intensity), and 22.1plus minus 1.3 Angstrom (interplanar d-spacing) and W (relative intensity). The X-ray diffraction pattern of calcined the MCM-22 family molecular sieve includes one or more of 3 values, e.g. 30.0plus minus 2.2 Angstrom (interplanar d-spacing) and W-M (relative intensity). The X-ray diffraction pattern of calcined MCM-22 family molecular sieve includes one or more of 6 values, e.g. 30.0plus minus 2.2 Angstrom (interplanar d-spacing) and W-M (relative intensity). EXAMPLE - Silicon oxide (SiO2)/aluminum oxide (Al2O3) ( approximately 30), water/SiO2 ( approximately 13), hydroxide ion/SiO2 ( approximately 0.15), sodium ion/SiO2 ( approximately 0.15), and hexamethyleneimine/SiO2 ( approximately 0.2) were crystallized at 170degreesC in an autoclave with stirring at 250 rpm for 24 hours. After crystallization, the hydrothermal reaction mixture slurry was filtered, washed with deionized (DI) water and dried at 120degreesC. The XRD patterns of the calcined material showed the typical pure phase of MCM-22 topology. The as-synthesized material had an XRD patterns including an additional peak (26.9degrees). The resulting MCM-22 crystals had crystallinity of 105%, a surface area of 612 m/g, a platelet morphology with an average crystal thickness of at least 300 Angstrom , a mesitylene uptake of 24.7 mg/g and a mesitylene sorption rate of 45 mg/g/min.
