Benzoic acid is scaly or needle shaped, with
the smell of benzene or formaldehyde,
flammable. The relative density is 1.2659. The
melting point is 122.4ºC, the boiling point is
249ºC, and the refractive index is 1.504.
Vapors are volatile. Flash point (close cup)
121-123ºC. Slightly soluble in water, soluble
in ethanol, methanol, ethyl ether, chloroform,
benzene, toluene, carbon disulfide, carbon
tetrachloride and turpentine. It sublimated
rapidly at 100 degrees and evaporated at the
same time as steam. Benzoic acid is widely
found in nature in the form of free acids,
esters or their derivatives. In the form of
free acid and benzyl ester, for example, in the
leaves and stems of some plants, there are free
forms in the leaves and stems of some plants,
in the form of methyl or benzyl esters in the
essence, and in the form of its derivative,
equine acid in horse urine.
