Embodiment 1

[0106] Weigh 852.4 g of deionized water into a 2L Teflon bottle. Place the bottle in a 4L beaker, add a stir bar, and begin stirring on a magnetic stir plate. 489.7 g of 97% 1,5 dibromopentane were added. Then 362.7 g of 97% 1-methylpyrrolidine were added. 1.5 L of water (room temperature (RT)) was placed between the bottle and beaker to help spread any exotherm. Let it mix overnight. 1697 g of a yellow solution were recovered.

Embodiment 2

[0108] Weigh 874.8 g of deionized water into a 2L Teflon bottle. Place the bottle in a 4L beaker, add a stir bar, and begin stirring on a magnetic stir plate. 474.1 g of 97% 1,5 dibromopentane (DBP) were added. Then 400.7 g of 99% 1-methylpiperidine were added. 1.5 L of water (RT) was placed between the bottle and beaker to help spread any exotherm. Let it mix overnight. In the morning there was no visible vortex, so not stirring well. Blend the mixture using a Heidolph high-speed mixer throughout the day. This slowly turned into a yellow solution. Mixing was stopped for 52 hours and then resumed for an additional 8 hours. The yellow solution yielded some clear unreacted DBP at the bottom, which was separated. Analysis showed the yellow solution to be 49.5% water.

Embodiment 3

[0110] Under overhead stirring, 1000 g of the product of Example 1 was loaded into a 3 neck round bottom flask. Add 295.4g of 99% Ag 2 O, and cover the flask with aluminum foil. It was mixed for 48 hours at room temperature. A glass filter was used to separate the clear yellow solution. Filter the solution several times over the next week or two. Analysis showed the solution to be 65.5% water.

Abstract

A new aluminosilicate zeolite designated UZM-50, methods of making the zeolite, and its use as a catalyst in hydrocarbon conversion processes are described. This zeolite is represented by the empirical formula M+ mRrA1-xExSiyOz where M is selected from the group consisting of hydrogen, sodium, potassium, magnesium, calcium or combinations thereof, R is the organic structure directing agent or agents derived from reactants R1 and R2 where R1 is an amine essentially incapable of undergoing pyramidal inversion and having 7 or fewer carbon atoms, and R2 is a dihaloalkane, and E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof. UZM-50 has utility in various hydrocarbon conversion reactions such as conversion of an aromatic molecule to another aromatic molecule.

Description

technical field [0001] The present invention relates to a novel aluminosilicate zeolite designated UZM-50 and its use as a catalyst in hydrocarbon conversion processes. The zeolite is represented by the following empirical formula: [0002] m + m R r Al 1-x E x Si y O z [0003] wherein M is selected from hydrogen, sodium, potassium, magnesium, calcium, or combinations thereof, and R is one or more organic structure directing agents derived from reactants R1 and R2, wherein R1 is substantially incapable of undergoing cone inversion and An amine having 7 or fewer carbon atoms, and R2 is a dihaloalkane, and E is an element selected from the group consisting of gallium, iron, boron, and mixtures thereof. UZM-50 has utility in various hydrocarbon conversion reactions such as the conversion of an aromatic molecule to another aromatic molecule. Background technique [0004] Zeolites are crystalline aluminosilicate compositions that are microporous and composed of horn-sh...
