Reaction Steps
To 900 grams of water, while under agitation, was added 180 grams of ethylene diamine, 60 grams of melamine and char and/or phase transfer catalysts as set forth in Table 4 below. The mixture was warmed to 170° F. and, while maintaining temperature, phosphoric acid was slowly added until a pH of 7.0 was reached. The mixture was cooled, filtered, dried and ground to recover the flame retardant.
