A charge of 500 grams of 37.7 percent hydrochloric acid was placed into a 500 milliliter, 3-neck flask fitted with a mechanical stirrer, a thermometer, and a reflux condenser. Into said reaction flask was then added 63 grams of melamine. The reaction mixture was heated to reflux and maintained at reflux for 1.5 hours. The reaction flask was then exposed to room temperature for a 16 to 17 hour period. The reaction product was filtered and washed with 300 milliliters of deionized water. The washed product was dried at 110° C. for 20 hours. Yield: 71 grams of melamine monohydrochloride (yield: 87.4%). Percent chlorine calculated: 21.8%; percent chlorine found: 22.6%.
