ABSTRACT:
A silica polymorph suitable for use in preparing an aromatic alkylation or isomerization catalyst is prepared by hydrothermally crystallizing said silica polymorph from a silicate solution containing an organic agent, in combination with a base solution, and an acid solution. Crystallization is effected utilizing high shear mixing followed by an unagitated period during the crystallization of said silica polymorph.
