Abstract:
1. A process for the preparation of an IM-12 crystallized solid that exhibits an x-ray diffraction diagram that includes at least the lines that are inscribed in the table below: where FF=very high; m=mean; f=low; F=high; mf=medium low; ff=very low and that exhibits a chemical composition that is expressed on an anhydrous base, in terms of oxide moles, defined by the following general formula: XO 2 :m YO 2 :p Z 2 O 3 :q R 2/n O in which R represents one or more cation(s) of valence n, X represents one or more tetravalent element(s) different from germanium, Y represents germanium, Z represents at least one trivalent element, whereby m, p and q respectively represent the mole number of YO 2 , Z 2 O 3 and R 2/n O, and m is between 0 and 1, p is between 0 and 0.5, and q is between 0 and 0.7, said process comprising initiating the mixing of at least one source of at least one XO 2 oxide, optionally at least one source of the YO 2 oxide, optionally at least one source of at least one Z 2 O 3 oxide, at least one nitrogen-containing organic cation R, or at least one precursor of the nitrogen-containing organic cation or at least one decomposition product of the nitrogen-containing organic cation and then in initiating the hydrothermal treatment of said mixture until said IM-12 crystallized solid is formed, with the proviso that R is the cation (6R,10S)-6,10-dimethyl-5-azoniaspiro[4,5]decane.
