Description

F-2238(2239) IMPROVED SYNTHESIS OF ZSM-23 ZEOLITE ABSTRACT There is disclosed a method for preparing a ZSM-23 crystalline zeolite wherein the organic template used in the synthesis has the formula: (CH3)3N+-R1-N+(CH3)3 wherein R1 is a saturated or unsaturated straight chain hydrocarbyl group containing seven carbon atoms. The template, designated herein Diquat-7? cation, can be obtained by dissolving a novel type of compound which can be the dihalide salt of the cation or the hydroxide derived from such a salt. Also disclosed is the as-synthesized form of ZSM-23 prepared by using the novel Diquat-7 template as well as catalyst compositions containing the ZSM-23 so synthesized. ZSM-23 is useful as a catalyst for catalytically converting an organic charge.
