SYNTHESIS OF ZEOLITE ZSM-22 WITH A HETEROCYCLIC ORGANIC COMPOUND ABSTRACT An improved process for preparing ZSM-22 zeolite from a novel reaction mixture is disclosed and claimed. The process comprises preparing a reaction mixture containing water and sources of an alkali metal or alkaline earth metal cation, alumina, silica, and a particular organic promoter, and maintaining the reaction mixture at crystallization conditions until crystals of the ZSM-22 zeolite are formed. Such a reaction mixture has the following composition, in terms of mole ratios of oxides: SiO2/Al2O3 = 20 to ? H2O/SiO2 = 10 to 100 OH-/SiO2 = 0 to 1.0 M+/SiO2 - 0 to 2.0 RN/SiO2 = 0.01 to 2.0 wherein M+ is alkali metal or alkaline earth metal cation and RN is the functional group of the organic promoter. The organic promoter is a heterocyclic organic compound containing one or more four (4) to ten (10) member, saturated or unsaturated, non-fused rings, wherein the hetero atoms are the same or different and can be oxygen, phosphorous or nitrogen, an alkyl and/or alkene derivative of such heterocyclic organic compounds, wherein the alkyl and/or alkene groups contain one (1) to ten (10) carbon atoms, or an organic or inorganic salt of or cation derived from the heterocyclic organic compound or its alkyl or alkene derivative. The zeolite ZSM-22 as synthesized from such a reaction mixture is also claimed.
