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.
ɪ k /) is a white (or colorless) solid organic compound with the formula C 6 H 5 COOH, whose structure consists of a benzene ring (C 6 H 6) with a carboxyl (−C(=O)OH) substituent. The benzoyl group is often abbreviated "Bz" (not to be confused with "Bn," which is used for benzyl ), thus benzoic acid is also denoted as BzOH, since the benzoyl ...
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.
