Sodium malonate (141-95-7) is used for raw material of pharmaceutical, dye and fragrance ; organic synthesis.
Derive by mixing malonic acid with sodium hydroxide solution; Industrial production often add chloroacetic acid with sodium cyanide to get cyanuric acid, and then through the role of liquid caustic soda sodium malonate. The chloroacetic acid dissolved in water at 15 ℃ below with saturated sodium carbonate solution to pH7.0, and then adding sodium cyanide solution at 45 ℃, at 105-110 ℃ reaction to 30min, adding 45-55% sodium hydroxide, reaction at the 100-105 ℃ 1.5h, concentrated solution of sodium malonic too dry to obtain Sodium malonate (141-95-7).
