Benzoic acid
There are industrial grade and BP grade, and our company has advantages in exporting both.
Benzoic acid is a scaly or needle-shaped crystal with the smell of benzene or formaldehyde. The melting point is 122.13ºC, the boiling point is 249ºC, and the relative density is 1.2659 (15/4ºC). It sublimates rapidly at 100°C, and its vapor is highly irritating and can easily cause coughing after inhalation. Slightly soluble in water, easily soluble in organic solvents such as ethanol and ether. Benzoic acid is a weak acid, stronger than fatty acids. They have similar chemical properties and can form salts, esters, acid halides, amides, acid anhydrides, etc., and are not easily oxidized. Electrophilic substitution reaction can occur on the benzene ring of benzoic acid, mainly obtaining meta-substitution products.
Usage
[Use 1] Used in the production of medicines, dye carriers, plasticizers, spices and food preservatives, etc., and also used to improve the performance of alkyd resin coatings
[Use 2] Mainly used for anti-corrosion and anti-corrosion
[Use 3] Used as chemical reagents and preservatives
[Use 4] Usually used as a fixative or preservative. Also used as a flavor preserving agent for fruit juice drinks. Can be used as an incense stick or as an incense stick. It can also be used in food flavors such as chocolate, lemon, orange, berries, nuts, candied fruits, etc. It is also commonly used in tobacco flavors.
[Use 5] Preservative; antimicrobial agent.
Due to the low solubility of benzoic acid, it must be fully stirred when used, or it must be dissolved in a small amount of hot water or ethanol. When used in concentrated fruit juices for refreshing drinks, benzoic acid is easily volatilized with water vapor, so its sodium salt is commonly used. 1g sodium salt is equivalent to 0.847g benzoic acid.
[Use 6] Benzoic acid is an important acid-type food preservative. Under acidic conditions, it has an inhibitory effect on mold, yeast and ~, but has a weak effect on acid-producing bacteria. The optimal pH value for bacteriostasis is 2.5~4.0, and generally a pH value lower than 4.5~5.0 is appropriate. In the food industry, the maximum usage amount of concentrated fruit and vegetable juices in plastic barrels shall not exceed 2.0g/kg; in jams (excluding cans), juice (flavored) beverages, soy sauce, and vinegar, the maximum usage amount shall be 1.0g/kg. ; In soft candies, wine, and fruit wine, the maximum usage amount is 0.8g/kg; in low-salt pickles, sauces, and preserves, the maximum usage amount is 0.5g/kg; in carbonated beverages, the maximum usage amount is 0.2g/kg. Since benzoic acid is slightly soluble in water, a small amount of ethanol can be used to dissolve it during use.
[Use 7] Benzoic acid is an important acid-type feed preservative. Under acidic conditions, the optimal pH for bacteriostasis is 2.5-4.0, generally lower than pH 4.5-5.0.
