|Claims:||1. A process for preparing crystalline calcium pseudomonate or a hydrate thereof which process comprises reacting pseudomonate ions with calcium ions in solution in an aqueous solvent, recovering a crystalline calcium pseudomonate hydrate from the solution and thereafter optionally removing water of crystallisation. |
2. A process according to claim 1 which comprises adding a source of calcium ions to a solution of pseudomonic acid or a salt thereof in an aqueous solvent.
