A method is provided for synthesizing a molecular sieve having the framework structure of SSZ-55 using [(1-phenyl)cyclopentylmethyl]trimethylammonium cations as a structure directing agent.
The present invention relates to new crystalline zeolite SSZ-55 prepared using a phenylcycloalkylmethyl ammonium or N-cyclohexyl-N-(2-methylpropyl)pyrrolidinium cation templating agents.
