Abstract

Official abstract text for this publication.

A molecular sieve having the framework structure of ZSM-5 is produced using one or more of 1,4-bis(N-pentylpyrrolidinium)butane dications, 1,5-bis(N-pentylpyrrolidinium)pentane dications, and 1,6-bis(N-pentylpyrrolidinium)hexane dications as a structure directing agent.

First claim

Opening claim text (preview).

The invention claimed is: 1. A molecular sieve having the structure of ZSM-5 and, in its as-synthesized form, comprising one or more of 1,4-bis(N-pentylpyrrolidinium)butane dications, 1,5-bis(N-pentylpyrrolidinium)pentane dications, and 1,6-bis(N-pentylpyrrolidinium)hexane dications in its pores, wherein said dications have one of the following formulas: 2. The molecular sieve of claim 1 and having a composition comprising the molar relationship: ( q )Q:X 2 O 3 :( n )YO 2 wherein 0<q/n≤0.05, n is at least 20, Q comprising one or more of 1,4-bis(N-pentylpyrrolidinium)butane dications, 1,5-bis(N-pentylpyrrolidinium)pentane dications, and 1,6-bis(N-pentylpyrrolidinium)hexane dications, X is a trivalent element, and Y is a tetravalent element. 3. The molecular sieve of claim 2 , wherein X includes aluminum, and Y includes silicon and/or germanium. 4. A process for converting a feedstock comprising an organic compound to a conversion product, said process comprising the step of contacting said feedstock at organic compound conversion conditions with a catalyst comprising a molecular sieve of claim 1 to form said conversion product.
