2 . 2 . 2 . The Boulle's process The Boulle's process is a metathesis reaction widely used for the preparation of water-soluble cyclotriphosphates. The starting material is silver cyclotriphos-phate monohydrate, A g 3 P 3 0 g . H 2 0 . This salt, sparingly water-soluble, is easily prepared by adding an aqueous solution of silver nitrate (~ M/10) to an aqueous solution of sodium cyclotriphosphate of approximately the same concentration.
