ABSTRACT:
A process for producing ZSM-48 comprises crystallizing an aqueous reaction mixture comprising at least one source of silica, at least one source of alumina, at least one source of hydroxyl ions, at least one source of diquaternary alkylammonium, R2+, ions having the formula:in-line-formulae description="In-line Formulae" end="lead"?(CH3)3N+(CH2)5N+(CH3)3in-line-formulae description="In-line Formulae" end="tail"?and optionally ZSM-48 seed crystals, wherein said reaction mixture has a composition including the following molar ratios:R2+:SiO2less than 0.1SiO2:Al2O3less than 100OH−:SiO2less than 0.2.
