Abstract: Provided is a crystalline layered silicate, having an X-ray diffraction pattern comprising reflections at 2-theta values of (5.3±0.2)°, (8.6±0.2)°, (9.8±0.2)°, (21.7±0.2)° and (22.7±0.2). Also provided are a process for preparing the crystalline layered silicate and uses of the layered silicate. The process comprises steps of: (i) preparing a synthesis mixture comprising water, a source of Si, and a structure directing agent comprising a diethyldimethylammonium compound; (ii) subjecting the synthesis mixture obtained from (i) to hydrothermal synthesis conditions comprising heating the synthesis mixture obtained from (i) to a temperature in the range of from 110 to 180° C. and keeping the synthesis mixture at a temperature in this range under autogenous pressure for 1 to 6 days, obtaining a mother liquor comprising the crystalline layered silicate.
