Benzoic acid is the simplest member of the aromatic carboxylic acid family. It is a weak acid that is a precursor for the synthesis of many important organic compounds. More than 90 percent of commercial benzoic acid is converted directly to phenol and caprolactam. Its use in the production of glycol benzoates for the application of plasticizer in adhesive formulations is
increasing. The organic compound is also used in the manufacture of alkyd resins and drilling mud additive for crude oil recovery applications. It is also used as a rubber polymerization activator, retardant, resins, alkyd paint, plasticizers, dyestuffs, and fibers. Benzoic acid and its esters occur in apricots, cranberries, mushrooms and jasmine plants. The history of benzoic acid
dates back to sixteenth century. In the year of 1875 Salkowski a prominent scientist discovered its antifungal abilities. In medicine, benzoic acid is the principal component of benzoin resin, and is a constituent of Whitfield’s ointment which is used for the treatment of fungal skin diseases such as tinea, ringworm, and athlete’s foot.

Scaly or needle like crystals. With the smell of formaldehyde or benzene. Slightly soluble in water, soluble in ethanol, methanol, diethyl ether, chloroform, benzene, toluene, CS2, CCl4 and turpentine.

Benzoic acid was found in the 16th century. In 1556, Nostradamus first described carbonization effect of benzoin; After the Alexius Pedemontanus and Brian blessed decipher were discovered in 1560 and 1596. In 1875, the salkowski discovered the antifungal potency of benzoic acid, so benzoic acid is used for long term preservation cloudberry.

Benzoic acid and sodium benzoate are commonly used food preservative. In acidic conditions, it has inhibitory effect on yeast and mold. When pH value is 3 antibacterial strength, when pH was 6 for a lot of mould effect is very poor, so the inhibition the optimum pH value is 2.5-4.0. In the food industry with plastic barrels concentrated fruit and vegetable juice, the maximum usage shall not exceed 2.0g/kg; in the jam (not including canned), fruit juice (taste) drinks, soy sauce, vinegar in the maximum amount
is 1.0g/kg; in Wine, candy, wine in the maximum amount of 0.8g/kg in the low salt; pickles, sauces, candied fruit, use the largest 0.5g/kg in carbonate; use the largest beverage 0.2g/kg. because of solubility of benzoic acid, when used will be stirring, or dissolved in a small amount of hot water or ethanol. The use of concentrated fruit juice in the soft drink used for benzoic acid
easily volatile with steam, it is commonly used in the sodium salt. Benzoic acid in food industry is a common preservative in dairy products, but not allowed to be added. In general, benzoic acid is considered to be safe. But for some special populations, including infants, long-term intake of benzoic acid may lead to asthma, urticaria, metabolic acidosis and other adverse reactions.
Paul deodorant benzoic acid is also used as a beverage. As the cream sweet perfume fragrance. Can also be used for chocolate, lemon, orange, sub berries, nuts, candied fruit and other edible flavor type. Tobacco flavor also commonly used. In addition of benzoic acid is also used as a pesticide, medicine, dye, mordant and plasticizer agent for the production of raw materials,
polyamide resin and alkyd resin modifying agent and steel equipment anti rust agent.
