Sodium benzoate also known as benzoate of soda is the sodium salt of benzoic acid, widely used as a food preservative (with an E number of E211) and a pickling agent. It appears as a white crystalline chemical with the formula C 6 H 5 COONa.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
For example, for three structural isomers with molecular formula C 5 H 12 the melting point increases in the series isopentane −160 °C (113 K) n-pentane −129.8 °C (143 K) and neopentane −16.4 °C (256.8 K). [15] Likewise in xylenes and also dichlorobenzenes the melting point increases in the order meta, ortho and then para.

In laboratory, copper benzoate can be made by combining aqueous solutions of potassium benzoate with copper sulfate. Hydrated copper benzoate precipitates as a pale blue solid: 4 C 6 H 5 CO 2 K + 2 CuSO 4 ·5H 2 O → Cu 2 (C 6 H 5 CO 2) 4 (H 2 O) 2 + 2 K 2 SO 4 + 8 H 2 O. The primary use of this compound is in the production of a blue flame in ...
Benzoic acid is often added to drinks as a preservative in the form of its salts sodium benzoate (E211), potassium benzoate (E 212), or calcium benzoate (E 213). [2]
