Abstract: Zeolite ZSM-12 has been synthesized by the hydrothermal method from the mixture of Na2O-Al2O3-SiO2-methyhriethylammonium iodide-H2O at 433K in a static autoclave.The products have SiO2/Al2O3≥32.2. The thermal stability and catalytic activity of ZSM-12 in the alkylation of benzene-ethylene have been examined.

Key words: ZSM-12 zeolite, sysnthesis, hydrothermal method, SiO2/Al2O3 ratio, characterization
