Abstract

The intercalation of acetic acid into the crystalline layered silicate octosilicate was found to take place efficiently and give a new type of layered structure. The highly crystalline RWR-type zeolite was successfully prepared by the dehydration–condensation of silanol groups on both sides of the interlayer of the acetic acid-intercalated octosilicate (Ac-octosilicate). The crystallinity of the RWR-type zeolite was strongly dependent on the amount of acetic acid molecules in the interlayer.
