Procedure

A saturated hot aqueous solution of phenylphosphonic acid (800 mmol, 126 g) is added to a saturated solution of melamine (800 mmol, 101.0 g) in 90° C. hot water under vigorous stirring. After 10 min, the reaction mixture is allowed to cool slowly to room temperature (later on to 4° C.) slowly. The procedure yields 205.0 g (721 mmol, 90.2%) of the desired product as colorless crystals (needles).
