<p>Crystalline, microporous gallium phosphate and its substituted derivatives, characterised by: a) the following approximate general formula: RrGagPpXxO2Ff.hH2O where the sum of g, p and x is equal to 1, and where: g is a number between 0.3 and 0.5, p is a number between 0.3 and 0.5, x is a number between 0 and 0.5, r is a number between 0.01 and 0.2 f is a number between 0.01 and 0.2 h varies, depending upon the degree of hydration of the solid, between 0 and 0.05 R is an organic compound, chosen from the group formed by the cyclic amines X is a heteroatom chosen from the group formed by the elements: Li, Be, Co, Mg, Mn, Zn, Al, B, Cr, Fe, Ge, Si, Ti, As, and V, b) an X-ray diffraction diagram represented in Table 1 of the description, and method for their preparation. d</p> |
