Abstract: A method for synthesizing a zeolite having an of MFI framework structure is provided. The method includes (i) preparing a reaction mixture comprising a source of aluminum, a source of silicon, a structure directing agent comprising 2,2-dipropylpentane-1-amine, a source of fluoride ions, and water; (ii) heating the reaction mixture under crystallization conditions including a temperature of from 100° C. to 200° C. for a time sufficient to form crystals of the aluminosilicate zeolite; and (iii) recovering the crystals of the aluminosilicate zeolite from the reaction mixture.
