Nonflammable

A solution of octadecyanoyl chloride (8 g), indichloromethane (40 mL) was treated with the crude octadecylamine with stirring. Triethylamine (15 mL) and hexane (100 mL) were added, and the solution was stirred at 45℃ for an hour. The solution was cooled and filtered, and the collected precipitate washed with methanol. The precipitate was recrystallized from dichloromethane, yielding N-octadecylstearamide (6.8 g) as a white powder.
