Reaction Steps

2,6-Diamino-4-chloro-s-triazine (100 g., 0.7 mole), octadecyl amine (207 g., 0.7 mole), and sodium carbonate (100 g) were dissolved in 1000 mls of dimethyl formamide and heated at 100° C. for 4 hours. While still hot, the contents of the reactor was filtered to remove the inorganic salts. When the hot filtrate was allowed to cool, the crude octadecyl melamine precipitated. With filtration, 208 grams (M.P. 78°-82° C.) of a pale yellow solid was recovered. Addition of the second filtrate to cold water yielded an additional 48 grams of solid (M.P. 60°-80° C.).
