Zusammenfassung:The present invention relates to a new process for synthesising a crystalline material comprising structure Beta zeolite in nanocrystalline form, and which can comprise at least the following steps: (i) preparing a mixture comprising at least one source of water, at least one source of a tetravalent element Y, at least one source of a trivalent element X, at least one source of an alkali cation or alkaline earth metal cation (A), and at least one organic molecule selected from a monocyclic quaternary ammonium R1R2CycloN+, and a quaternary ammonium substituted with a cycloalkyl group R3R4R5R6N+. The molar composition of the mixture is:nX2O3: YO2:aA :mOSDA1 :zH2O; ii) crystallising the mixture; and iii) recovering the crystalline material.
