Abstract
Crystalline Group IIIB metallophosphates are provided herein having a composition in terms of mole ratios of oxides in the synthesized state of: X(M'.sub.2 O):Y(M.sub.2 O.sub.3):Z(P.sub.2 O.sub.5):nH.sub.2 O (I) wherein M' is an alkali metal; M is a Group IIB metal; x/y is a number from about 1.1 to about 1.9; z/y is a number from about 1 to about 1.9 n/y is a number from about 0 to about 8. Also provided is the use of these metallophosphates as ion exchange materials.

- X(M'.sub.2 O):Y(M.sub.2 O.sub.3):Z(P.sub.2 O.sub.5):nH.sub.2 O (I)
- wherein
- M' is an alkali metal;
- M is a Group IIIB metal;
- x/y is a number from about 1.1 to about 1.9;
- z/y is a number from about 1 to about 1.9
- n/y is a number from about 0 to about 8.
A process for preparing a crystalline Group IIIB metallophosphates having a composition in terms of mole ratio of oxides in the synthesized state of:
- X(M'.sub.2 O):Y(M.sub.2 O.sub.3):Z(P.sub.2 O.sub.5):nH.sub.2 O (I)
- wherein
- M' is an alkali metal;

- x/y is a number from about 1.1 to about 1.9;
- z/y is a number from about 1 to about 1.9
- n/y is a number from about 0 to about 8,
- said process comprising wherein a source of phosphorus is added to a solution containing a Group IIIA metal source, stirring said solution, adding to said solution an alkali cation source to form a reaction mixture, heating said reaction mixture at a temperature of at least 70.degree. C. under autogeneous pressure until crystals are formed, and recovering said crystals from said reaction mixture.
