Embodiment 1
[0061] The aluminosilicate solution was prepared as follows: 39.81 grams of aluminum hydroxide (28.22% Al) and 1371.36 grams of propyltrimethylammonium hydroxide, 21.9% solution were first mixed under vigorous stirring. After mixing well, add 952.5 grams of Ludox TM AS-40 (39.8% SiO 2 ). The reaction mixture was homogenized with a high speed mechanical stirrer for an additional hour and placed in the oven at 100°C overnight. Analysis showed that the resulting aluminosilicate solution contained 7.58% by weight Si and 0.49% by weight Al, resulting in a Si / Al ratio of 14.86.
[0062] To 1000 gram portions of the aluminosilicate solution prepared in Example 1 was added an aqueous NaCl solution containing 21.16 g of NaCl (98%) dissolved in 100.0 g of distilled water with vigorous stirring and the reaction mixture was rehomogenized 30 minutes. A 1067 gram portion of the reaction mixture was transferred to a 2000 mL Parr stainless steel autoclave, which was heated to 175°C and h...
Embodiment 2
[0070] To 1000 gram portions of the aluminosilicate solution prepared in Example 1 was added an aqueous NaCl solution containing 15.87 g of NaCl (98%) dissolved in 100.0 g of distilled water with vigorous stirring and the reaction mixture was rehomogenized 30 minutes. A 1050 gram portion of the reaction mixture was transferred to a 2000 mL Parr stainless steel autoclave, which was heated to 175°C and held at this temperature for 168 hours. The solid product was recovered by filtration, washed with deionized water and dried at 100°C.
[0071] The product was identified as UZM-37 by xrd. Representative diffraction lines observed for the products are shown in Table 3. The composition of the product was determined by elemental analysis to consist of the following molar ratios: Si / Al=13.21, Na / Al=0.45, N / Al=1.37, C / N=5.90. A portion of the material was calcined by raising the temperature to 600° C. for 2 hours in air followed by 2 hours in air. The BET surface area was found to...
Embodiment 3
[0075] The aluminosilicate solution was prepared as follows: 13.27 grams of aluminum hydroxide (28.22% Al) and 457.12 grams of propyltrimethylammonium hydroxide, 21.9% solution were first mixed under vigorous stirring. After mixing well, add 317.50 grams of Ludox TM AS-40 (39.8% SiO 2 ). The reaction mixture was homogenized with a high speed mechanical stirrer for an additional hour and placed in the oven at 100°C overnight. Analysis showed that the resulting aluminosilicate solution contained 7.71% by weight Si and 0.49% by weight Al, resulting in a Si / Al ratio of 15.15.
[0076] 790 gram portions of this aluminosilicate solution were placed in a container, and an aqueous NaCl solution containing 16.71 g of NaCl (98%) dissolved in 80.0 g of distilled water was added under vigorous stirring, and the reaction mixture was homogenized for a further 30 minute. An 850 gram portion of the reaction mixture was transferred to a 2000 mL Parr stainless steel autoclave, which was he...
