The invention relates to a synthetic stratified material, MCM-56, having a composition determined by the following molar relation: X 2 O 3: (n) YO 2, wherein n ranges from 5 to 35, preferably from 5 to 25 and more preferably from 10 to 20, X is a trivalent element selected from aluminium, boron, iron and gallium, preferably aluminium, and Y is a tetravalent element selected from silicon and germanium, preferably silicon, the material being characterized by an absorbtion capacity of the 1, 3, 5 - trimethylbenzene of at least 35 miu l/ g of calcinated synthetic material, an initial absorbtion of 15 mg of 2,2 - dimethylbutane/g of calcinated synthetic material, in less than 20 s and an X-ray diffraction pattern of the calcinated synthetic material having the maximum spacing " d" at 124 +- 02; 99 +-03; 69 +- 01; 62 +- 01; 355 +- 007 and 342 +- 007 A
