Abstract
The invention provides a method for synthesizing a porous inorganic solid comprising the steps of: (a) forming a reaction mixture containing water, an alumina source, a silica source, an alkali metal oxide source, and a diquaternary ammonium salt having the formula: ##STR1## wherein R is a diamondoid group, n is from about 1 to about 50, and X is an anion which is not detrimental to the formation of said porous inorganic solid; and PA1 (b) recovering a porous inorganic solid from said reaction mixture.
