Product Introduction:

Benzoic acid is commonly known as benzoic acid, and its molecular formula is C6H5COOH, Benzoic Acid Powder. It is tasteless or has a slightly resting fragrance. It is hardly soluble in water at room temperature (the solubility is 0.34g/100mL at 20°C, and 4.55/100ml at 90°C), and it is soluble in organic solvents such as ethanol and propanol.

Benzoic Acid Powder is slightly volatile under hot air, and it sublimates quickly at 100°C. Because its vapor is very irritating, it can easily cause coughing after inhalation. Benzoic Acid Powder is slightly soluble in water and easily soluble in organic solvents such as ethanol, ether, chloroform, benzene, toluene, carbon disulfide, carbon tetrachloride and turpentine. Because Benzoic Acid Powder has poor water solubility, it is usually used as a sodium salt.

Benzoic acid is a monobasic aromatic carboxylic acid, relatively weakly acidic. The pH of its 25% saturated aqueous solution is 2.8, so its bactericidal and antibacterial efficacy will increase as the acidity of the medium increases.

Benzoic Acid Powder loses its bactericidal and antibacterial effects in alkaline medium. When the pH is 3.5, a 0.125% solution can kill Staphylococcus and other bacteria within 1 hour. When the pH is 4.5, the minimum inhibitory concentration for general fungi is about 0.1%. When the pH is 5, even a 5% solution, The bactericidal effect is not reliable. The optimal pH of Benzoic Acid Powder for antiseptic is 2.5-4.0.

Product function:

  1. The benzoic acid powder can be used as a preservative for food, feed, latex and toothpaste.
    • Under acidic conditions, it has an inhibitory effect on molds, yeasts and bacteria, but has a weaker effect on acid producing bacteria.
    • Because the molecular antibacterial activity of benzoic acid is higher than that of ionic antibacterial activity, when the pH value is less than 4, the antibacterial activity is high, and the optimum pH for antibacterial activity is 2.5-4.0, generally 4.5-. The pH is 5.0.
  2. The benzoic acid powder can be used as a fixing agent for fruit juice drinks.
    • It can be used as an ointment or as the essence of aromatherapy. It can also be used in edible flavors such as chocolate, lemon, orange, raspberry, nuts and candied fruit.
    • The solubility of benzoic acid powder is low, it should be fully stirred or dissolved in a small amount of hot water or ethanol. Benzoic acid powder is often volatilized by water vapor when used in soda juice concentrates, so sodium salt is often used.
  3. Benzoic acid powder can be used as an intermediate for the production of important plasticizers such as parabens and phthalates.
    • Benzoic acid can be prepared by bromination reaction to prepare bromobenzoic acid, and meta-bromobenzoic acid can be used as a binder for electrophotographic materials. It can also be used as intermediates for medicines and dyes, as well as for the preparation of plasticizers and perfumes.
  4. After adding benzoic acid powder to alkyd resin, the film thickness dries quickly, but it is not solvent resistant like styrene. The gloss, hardness and water resistance of the modified alkyd resin film have been improved. It can also be used as a dyeing agent for dyeing and printing.
  5. Benzoic acid powder reacts with diethylene glycol, triethylene glycol, and dipropylene glycol to produce important commonly used resin plasticizers, diethylene glycol dibenzoate (DEDB) and triethylene glycol dibenzoate (TEDB). Increase. Resins, coatings and adhesives.

Global benzoic acid market demand analysis:

At present, Benzoic Acid Powder is widely used in various industries. As people’s demand for chemical products increases, it will surely drive the increase in the market demand for Benzoic Acid Powder. It is mainly used as a bacteriostatic agent for latex, toothpaste, jam or other foods.

Benzoic Acid Powder can be used in the production of benzoyl chloride, benzophenone, benzoyl peroxide and paint industry. It can also be used as an intermediate for pharmaceuticals and dyes, for the preparation of plasticizers and spices, etc., and also as a rust inhibitor for steel equipment.

Nowadays, a large part of benzoic acid in the world is used as self-contained products, producing various esters and velutol, etc., which are mainly used for food and medical purposes, and are also widely used in resins, engineering plastics and basic chemicals.
