Abstract
The present invention relates to new crystalline molecular sieve SSZ-65 prepared using 1-[1-(4-chlorophenyl)-cyclopropylmethyl]-1-ethyl-pyrrolidinium or 1-ethyl-1-(1-phenyl-cyclopropylmethyl)-pyrrolidinium cation as a structure-directing agent, methods for synthesizing SSZ-65 and processes employing SSZ-65 in a catalyst.
Claims22
A molecular sieve having a mole ratio greater than about 15 of (1) an oxide of a first tetravalent element to (2) an oxide of a trivalent element, pentavalent element, second tetravalent element which is different from said first tetravalent element or mixture thereof and having, after calcination, the X-ray diffraction lines of Table II.
A molecular sieve having a mole ratio greater than about 15 of (1) an oxide selected from the group consisting of silicon oxide, germanium oxide and mixtures thereof to (2) an oxide selected from aluminum oxide, gallium oxide, iron oxide, boron oxide, titanium oxide, indium oxide, vanadium oxide and mixtures thereof, and having, after calcination, the X-ray diffraction lines of Table II.

- >15
- M2/n/YO2
- 0.01–0.03
- Q/YO2
- 0.02–0.05
- wherein Y is silicon, germanium or a mixture thereof;
- W is aluminum, gallium, iron, boron, titanium, indium, vanadium or mixtures thereof;
- c is 1 or 2;
- d is 2 when c is 1 or d is 3 or 5 when c is 2;
- M is an alkali metal cation, alkaline earth metal cation or mixtures thereof;
- n is the valence of M;
- and Q is a 1-[1-(4-chlorophenyl)-cyclopropylmethyl]-1-ethyl-pyrrolidinium or 1-ethyl-1-(1-phenyl-cyclopropylmethyl)-pyrrolidinium cation.
A method of preparing a crystalline material comprising (1) an oxide of a first tetravalent element and (2) an oxide of a trivalent element, pentavalent element, second tetravalent element which is different from said first tetravalent element or mixture thereof and having mole ratio of the first oxide to the second oxide greater than 15, said method comprising contacting under crystallization conditions sources of said oxides and a structure directing agent comprising a 1-[1-(4-chlorophenyl)-cyclopropylmethyl]-1-ethyl-pyrrolidinium or 1-ethyl-1-(1-phenyl-cyclopropylmethyl)-pyrrolidium cation.
