Abstract

A method of producing zeolites particularly ZSM-5 and ZSM-11 by strictly controlling the composition of the forming bath such that no organic is required. In a preferred embodiment the forming bath can contain seeds, lower aliphatic alcohols and/or ammonium hydroxide. The as-crystallized product has no organic in its pore structures and has a relatively low silica to alumina ratio.
