High quality Benzoic acid cas 65-85-0
Benzoic acid is also known as benzoic acid, whose molecular formula is C6H5COOH.
The simplest aromatic acid whose carboxyl group is directly linked to
the carbon atom of the benzene ring is a compound formed
when a hydrogen on the benzene ring is replaced by a carboxyl group (-cooh).
Is a colorless, tasteless flake crystal.
Melting point is 122.13 ℃, boiling point 249 ℃, relative density 1.2659 (15/4 ℃).
At 100 ℃ sublimation rapidly, its steam has a strong irritating, easy cause cough after inhaling.
Slightly soluble in water, easily soluble in ethanol, ether, chloroform, benzene, toluene, carbon disulfide,
carbon tetrachloride and turpentine and other organic solvents.

1. Benzoic acid is an important acid food preservative.
Under acidic conditions, it has an inhibitory effect on mold, yeast and bacteria,
but a weak effect on acid-producing bacteria.
The optimal pH value for bacteriostasis is 2.5 ~ 4.0, generally 4.5 ~ 5.0 lower than the pH value.
3. Due to the small solubility of benzoic acid,
it must be fully stirred or dissolved in a small amount of hot water or ethanol.
Benzoic acid tends to evaporate with water vapor when used in
concentrated juice for cool drinks, so it is often used as sodium salt.
One gram of sodium is equivalent to 0.847 grams of benzoic acid.
4.Usually used as a deodorant or as a preservative.
Also used as a deodorant in juice drinks.
It can be used as perfume for perfume essence.
Can also be used in chocolate, lemon, orange, berry, nuts,
preserves and other edible flavor.
Tobacco flavor is also commonly used.
