Production method
1. It can be obtained by neutralizing malonic acid with sodium hydroxide solution.
2. In industrial production, chloroacetic acid is often reacted with sodium cyanide to produce cyanoacetic acid, and thensodium malonate is obtained by liquid-alkali reaction. The chloroacetic acid was dissolved in water, neutralized with saturatedsodium carbonate solution to pH7.0 below 15℃, then sodium cyanide solution was added at 45℃, reacted at 105-110℃ for 30min, 45-55% sodium hydroxide was added, reacted at 100-105℃ for 1.5h, and the solution was concentrated and dried to obtain sodium malonate.
Use
Raw materials for medicines, dyes and fragrances. Sodium malonate is esterified with butanol to obtain dibutyl malonate, which is used to produce sulfa-6-methoxil. Esterified with ethanol to obtain diethyl malonate, which is used to produce hypnotic barbiturate; It is also used in the production of synsulfonic acid. For organic synthesis.
Disodium malonate Production
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).
