Abstract

A method for making crystalline aluminosilicate ZSM-34 zeolites, useful as catalysts for making C.sub.2 -C.sub.4 -olefins from methanol, from a reaction mixture containing silicon, aluminum, sodium, potassium, and an organic template compound which is (i) a salt of an ammonium compound of di-, tri-, or tetra-ethanolamine or (ii) a mixture of at least one of diethanolamine and triethanolamine with certain lower alkanols, lower alkylene diols, or lower alkyl iodides, sulfates, or p-toluenesulfonates.
