Reaction Steps
A charge of 1,700 grams of 48 percent hydrobromic acid solution was placed into a five-liter, three-neck flask fitted with a mechanical stirrer, a thermometer, and a reflux condenser. Into said flask was then added 252 grams of melamine and the reaction mixture was heated to reflux. The reflux condition was maintained for one hour. The reaction flask was then exposed to ambient temperatures for about 16 to 17 hours. The reaction product was filtered. Said filtered product was dried at 110° C. for 44 hours. Yield: 573 grams of melamine dihydrobromide (99.5 percent yield). Percent bromine calculated: 55.5%, percent bromine found: 55.8%.
