Safety Information
Calcium benzoate Usage And Synthesis
| Description | Calcium benzoate refers to the calcium salt of benzoic acid. When used in the food industry as a preservative, its E number is E213 (INS number 213); it is approved for use as a food additive in the EU, USA and Australia and New Zealand.
The formulas and structures of calcium carboxylate derivatives of calcium and related metals are complex. Generally the coordination number is eight and the carboxylates form Ca-O bonds. Another variable is the degree of hydration. |
| Chemical Properties | White or colorless orthorhombic crystals or a white powder. It has slight solubility in water and high solubility in hot water. The compound is highly stable at room temperature. |
| Uses | Calcium benzoate hydrate is used in used in the food industry as a preservative. It is also utilized as a preservative and growth promoter in the feed industry. |
| Preparation | Calcium benzoate is prepared by reacting benzoic acid and calcium bicarbonate. |
| Flammability and Explosibility | Not classified |
| Purification Methods | Calcium benzoate (3H2O) [2090-05-3] M 336.4. Recrystallise it from water (10m/g) between 90o and 0o. [Beilstein 9 I 60, 9 H 85, 9 III 377, 9 IV 280.] |
