Методика

1200 grams of water was warmed to 130° F. To this, while being agitated, was added 100 grams of melamine (2,4,6-triamine-1,3,5-triazine) and a char and/or phase transfer catalyst as set forth in Table 2-B below. The mixture was then warmed to 150° F. and 104.5 grams of tetrasodium pyrophosphate was added. The mixture was heated to 170° F. and the slow addition of 200 grams of twenty degree Baumé muriatic acid was started. Warming was continued until to 200° F., at which time cooling is started. When cooled to 70° F., the mixture was filtered, dried and ground to recover the flame retardant.
