【Raw materials of Sodium Benzoate】
Sodium hydroxide-->Toluene-->Sodium carbonate-->Sodium bicarbonate-->CARBON DIOXIDE-->Activated carbon,decolor-->Benzoic acid
【Production of Sodium Benzoate】
Sodium benzoate is produced by the neutralization of benzoic acid with sodium hydroxide. Sodium benzoate can also be prepared by adding benzoic acid to a hot concentrated solution of sodium carbonate until effervescence ceases. The solution is then evaporated, cooled and allowed to crystallize or evaporate to dryness, and then granulated.
1. Neutralized by benzoic acid and sodium bicarbonate. Put water and sodium bicarbonate into the neutralizing pot, boil it and make it dissolved into sodium bicarbonate solution. Mix it with benzoic acid until PH value of the reaction solution reaches to 7-7.5. Heat it to emit over carbon dioxide, and then add active carbon to decolorize it for half an hour. Do suction filtration, after filtrate gets concentrated, put it into flaker tray, dry it to be sheets in the drum, crush it, and then sodium benzoate is made. Consumption rate of benzoic acid (99.5%) 1045kg/t and sodium bicarbonate (98%) 610kg/t.
2. Use 32% soda solution to neutralize benzoic acid in the pot to reach PH value of 7.5, and neutralization temperature is 70℃. Use 0.3% active carbon to decolorize the neutralized solution, vacuum filter it, concentrate, dry it and then it comes to powdered sodium benzoate.
C6H5COOH+Na2CO3→C6H5COONa
3. To get it by toluene oxidation made benzoic acid reacting with sodium bicarbonate, sodium carbonate or sodium hydroxide.
