We have succeeded in the synthesis of a thermostable zeolite with a novel framework structure (CDS-1: Cylindrically Double Saw-edged zeolite; CDO topology) from a novel layered silicate (PLS-1: Pentagonal-cylinder Layered Structure) by topotactic dehydration-condensation between pure silicate layers consisting of face sharing of pentagon cylinders. The purely siliceous zeolite CDS-1 has a chemically inert silicate framework and consequently no acid sites. In order to expand the catalytic potential of CDS-1, incorporation of various metals into the zeolite framework is necessary. In this study, we tried to prepare the Al containing CDS-1 zeolite (Al-CDS-1) by (1) alumination of CDS-1 zeolite and (2) transformation of Al-PLS-1. The catalytic performance was also evaluated by a few test reactions such as 1-hexene and cumene cracking and dehydration of 2-propanol.
