“MSE” is one of the known “framework type codes (FTCs)” approved by International Zeolite Association (IZA)1). The IZA recommendation is that the FTC should be in bold text, but plain text is used here for simplicity. MCM-68 is a typical zeolite with the MSE framework (“type material” of MSE)1) first synthesized by Mobil researchers2). UZM-353) and YNU-24) are related materials with the same MSE topology. Organic structure-directing agents (OSDAs) are used in syntheses of MSEs, incorporating the organic cation N,N,N’,N’-tetraethylbicyclo[2.2.2]oct-7-ene-2,3:5,6-dipyrrolidinium (TEBOP2+) as shown in Fig. 1 (left) for the syntheses of MCM-68 and YNU-2, and Me2Pr2N+ (Fig. 1, right) for UZM-35. The MSE is an example of a new multi-dimensional framework with a 12-1010-ring pore system, which contains a straight 12-ring channel (Fig. 2(a)) that intersects with two independent tortuous 10-ring channels as well as an 18×12ring supercage (Fig. 2(b)) accessible only through the 10-ring channels5). This framework also possesses eight distinct T-sites1),5). Zeolites of this type in H+form are known to exhibit unique catalytic properties6),7) and are potentially useful as shape-selective catalysts for the alkylation of aromatics8),9), disproportionation of ethylbenzene and bifunctional isomerization of nalkanes10) as well as for the production of propylene by 288 Journal of the Japan Petroleum Institute, 60, (6), 288-300 (2017)
