Abstract

Official abstract text for this publication.

A method is disclosed for preparing molecular sieve SSZ-85 in the absence of a source of fluoride ions.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of preparing molecular sieve SSZ-85 comprising contacting under crystallization conditions a reaction mixture comprising a source of cobalt, a source of aluminum, a source of phosphorus, and an ionic liquid comprising a 1,3-diisopropylimidazolium cation; wherein the reaction mixture is substantially free of fluoride ions. 2. The method of claim 1 , wherein the reaction mixture has a composition, in terms of molar ratios, as follows: CoO/Al 2 O 3 0.05 to 0.5  P 2 O 5 /(CoO + Al 2 O 3 ) 0.5 to 1.5 [Q + A − ]/(CoO + Al 2 O 3 )  1 to 100 wherein [Q + A − ] represents an ionic liquid comprising a 1,3-diisopropylimidazolium cation (Q + ) and an anion (A − ) which is not detrimental to the formation of the molecular sieve. 3. The method of claim 1 , wherein the reaction mixture has a composition, in terms of molar ratios, as follows: CoO/Al 2 O 3 0.05 to 0.5  P 2 O 5 /(CoO + Al 2 O 3 ) 0.8 to 1.2 [Q + A − ]/Al 2 O 3   2 to 50. wherein [Q + A − ] represents an ionic liquid comprising a 1,3-diisopropylimidazolium cation (Q + ) and an anion (A − ) which is not detrimental to the formation of the molecular sieve. 4. The method of claim 1 , wherein the crystallizations conditions include a temperature of from 100° C. to 135° C.
