실험 절차

A solution of methylphosphonic acid (28.8 parts, 0.3 mol) in water (50 milliliters) is added dropwise to a suspension of melamine (37.8 parts, 0.3 mol) in water (500 milliliters) at refluxing temperatures over 30 mins. A clear solution is formed. Heating is continued for a further 2 hours and the reaction mixture is evaporated to dryness under reduced pressure. The solid product is collected, washed with methanol and dried at 80° C. under vacuum to give 64 parts of methylphosphonic acid melamine salt having melting point >250° C.
