[0131] Samples of UZM-39 were prepared as follows. 6.02g NaOH (97%) was dissolved in 125.49g water. 0.62gAl(OH) 3 (29.32 wt.% Al) was added to the NaOH solution to form a first solution. Separately, 0.24 g of layered material UZM-8 was stirred into 30.0 g of Ludox AS-40 to form a second solution. Add the second solution to the first solution. The mixture was cooled to 0°C-4°C. Separately, 6.54 g of 1,4-dibromobutane (99 wt.%) was mixed with 7.65 g of 1-methylpyrrolidine (97 wt.%) to form a third solution. The third solution was added to the cooled mixture of the first and second solutions to form the final reaction mixture. The final reaction mixture was transferred to a 300cc stirred autoclave and digested for 144 hours at 160°C and 100 rpm stirring. The product was isolated by filtration. The product was identified as UZM-39 by XRD, as figure 1 shown in . Analysis results showed that the material had the following molar ratios: Si / Al 12.64, Na / Al 0.116, N / Al 0.92, C...

[0141] 6.40 g NaOH (97%) was dissolved in 111.88 g water. 1.16g Al(OH) 3 (29.32 wt.% Al) was added to the sodium hydroxide solution to produce a first solution. Separately, 0.30 g of layered material (UZM-8) was stirred into 37.5 g of Ludox AS-40 to form a second solution. The second solution was added to the first solution and stirred vigorously for 1-2 hours. The mixture was cooled to 0°C-4°C. Separately, 8.18 g of 1,4-dibromobutane (99 wt.%) was mixed with 9.56 g of 1-methylpyrrolidine (97 wt.%) to form a third solution. The third solution was added to the cooled mixture to produce the final reaction mixture. The final reaction mixture was stirred vigorously and transferred to a 300cc stirred autoclave. The final reaction mixture was digested for 144 hours at 160°C with stirring at 100 rpm. The product was isolated by filtration. The product was identified as UZM-39 by XRD. Analysis results showed that the material had the following molar ratios: Si / Al 12.07, Na / Al ...

[0143] 7.19 g NaOH (99 wt.%) was dissolved in 90.1 g water. 1.56g Al(OH) 3 (29.32 wt.% Al) was added to the sodium hydroxide solution to produce a first solution. Separately, 0.405 g of layered material (UZM-8) was stirred into 50.62 g of Ludox AS-40 to form a second solution. The second solution was added to the first solution and stirred vigorously for 1-2 hours. The mixture was cooled to 0°C-4°C. Separately, 11.04 g of 1,4-dibromobutane (99 wt.%) was mixed with 12.90 g of 1-methylpyrrolidine (97 wt.%) to form a third solution. The third solution was added to the cooled mixture to produce the final reaction mixture. The final reaction mixture was stirred vigorously for 5 minutes and transferred to a 300cc stirred autoclave. The final reaction mixture was digested for 144 hours at 160°C with stirring at 100 rpm. 16.5 g of product were isolated by filtration. The product was identified by XRD as UZM-39 containing a very small amount of MOR impurities. Analysis results ...
