Abstract
Microporous crystallized gallium phosphate and its substituted derivatives, characterized by: PA1 a) the following approximate general formula: EQU R.sub.r Ga.sub.g P.sub.p X.sub.x O.sub.2 F.sub.f hH.sub.2 O PA1 where the sum of g, p and x is equal to 1, and where PA2 g is a number from 0.3 to 0.5, PA2 p is a number from 0.3 to 0.52, PA2 x is a number from 0 to 0.4, PA2 r is a number from 0.01 to 0.2, PA2 f is a number from 0.01 to 0.2, PA2 h varies according to the degree of hydration of the solid, from 0 to 0.5. PA2 R is an organic compound selected from the group formed by cyclic amines, PA2 X is a heteroatom selected from the group formed by the elements: Li, Be, Co, Mg, Mn, Zn, Al, B, Cr, Fe, Ge, Si, Ti, As and V PA1 b) an X-ray diffraction diagram shown in Table 1 of the description, and a method of preparing them.
