Synthesis of ZSM-35

A method for using dimethylpiperazine to synthesize ZSM-35, said method comprising (i) preparing a mixture capable of forming said ZSM-35, said mixture comprising sources of alkali or alkaline earth metal (M), an oxide of trivalent element (X), an oxide of tetravalent element (Y), water and directing agent (R) of 1,4-dimethylpiperazine, and having a composition, in terms of mole ratios, within the following ranges:

• ______________________________________ YO.sub.2 /X.sub.2 O.sub.3 1 to 100 H.sub.2 O/YO.sub.2 10 to 100 OH.sup.- /YO.sub.2 0 to 0.25 M/YO.sub.2 0 to 2.0 R/YO.sub.2 0.18 to 2.0 ______________________________________
• (ii) maintaining said mixture under sufficient conditions until crystals of said material are formed;
• and (iii) recovering said crystalline material from step (ii).
