| Sodium benzoate Usage And Synthesis |
| description |
Sodium benzoate, also known as benzoic acid sodium, is commonly used as food preservatives in food industry, odorless or with slight smell of benzoin, and tastes sweet astringency. Stable in air, can absorb moisture in open air. It’s naturally found in blueberry, apple, plum, cranberry, prunes, cinnamon and cloves, with weaker antiseptic performance than benzoic acid. Antiseptic performance of 1.180g sodium benzoate is equivalent of about 1g benzoic acid. In acidic environment, sodium benzoate have obvious inhibitory effect on a variety of microorganisms: when pH is at 3.5, 0.05% solution can completely inhibit the growth of yeast; while when pH is above 5.5, it has poor effect on a lot of mold and yeast; hardly has any effect in alkaline solution. After sodium benzoate enters into the body, in the process of biotransformation, it would combine with glycine to be uric acid, or combine with glucuronic acid to be glucosiduronic acid, and all to be eliminated from the body in urine, not to accumulate in the body. As long as it is within the scope of the normal dosage, it would be harmless to the human body, and it is a safe preservatives. It also can be used for carbonated beverages, concentrated juice, margarine, chewing gum base, jam, jelly, soy sauce, etc. Human acceptable daily intake (ADI) < 5 mg/kg body weight (take benzoic acid as calculation basis). Sodium benzoate has big lipophilicity, and it is easy to penetrate cell membrane into the cells, interfere in permeability of cell membrane, and inhibit cell membrane’s absorption of amino acids; cause Ionization acidification of alkaline storage in the cell when entering into, inhibit activity of respiratory enzymes, and stop condensation reaction of acetyl coenzyme A, and thereby achieve the purpose of food antiseptic. The above information is edited by the Chemicalbook He Liaopu. |
| Chemical properties | White crystals or granules, or colorless powder, with sweet astringency. Soluble in water, ethanol, glycerol and methanol. |
| Uses |
1. Sodium benzoate is also an important preservative of acid type food. It transforms into effective form of benzoic acid during application. See benzoic acid for application range and dosage. In addition, it also can be used as fodder preservative. 2. Preservatives; antimicrobial agent. 3. Sodium benzoate agent is a very important preservative of acid type fodder. It transforms into effective form of benzoic acid during application. See benzoic acid for application range and dosage. In addition, it also can be used as food preservative. 4. Used in the research of pharmaceutical industry and plant genetic, also used as dye intermediates, fungicide and preservatives. 5. The product is used as food additive (preservative), fungicide in pharmaceutical industry, dye mordant, plasticizer in plastic industrial, and also used as organic synthetic intermediate of spices and others. |
| Content Analysis | Take dried sample 1.5g into a 250ml conical flask, dissolve it with 25ml water, and then add 50ml ether and bromophenol. |
| Toxicity |
ADI 0～5mg/kg (take benzoic acid as calculation basis, total value of ADI including benzoic acid and its salts and esters; FAO/WHO, 2001). LD50 4070mg/kg (rats, by oral). GRAS(FDA，§184．1733，2000). |
| Production methods |
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. |

| Uses | Vasodilator |
| Uses | A benzene compound used as a synthetic reagent. |
| Definition | ChEBI: An organic sodium salt resulting from the replacement of the proton from the carboxy group of benzoic acid by a sodium ion. |
| Uses | Antimicrobial agent, flavoring agent and adjuvant in food; not to exceed a maximum level of 0.1% in food (21 CFR, 184.1733, 582.3733). Antifungal and bacteriostatic preservative in pharmaceuticals at concentrations of ~0.1%. Clinical reagent (bilirubin assay). |
