Abstract
There is provided a method for preparing a synthetic crystalline material from a reaction mixture including an organic directing agent selected from 1,4-diazacycloheptane (i.e. homopiperazine), azacyclooctane (i.e. heptamethyleneimine), aminocyclohexane (i.e. cyclohexylamine), aminocyclopentane (i.e. cyclopentylamine) and aminocycloheptane (i.e. cycloheptylamine). The crystalline material may be an aluminosilicate zeolite having considerable catalytic activity, e.g. for hydrocarbon conversion reactions.
