Product Description

Product Description

Acetic acid is an organic compound with the chemical formula CH3COOH. It is an organic monobasic acid and the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless, hygroscopic liquid with a freezing point of 16.6°C (62°F). After solidification, it becomes colorless crystals. Its aqueous solution is weakly acidic and highly corrosive, and is highly corrosive to metals. Vapor is irritating to eyes and nose.

Acetic acid is widely distributed in nature. For example, in fruit or vegetable oils, acetic acid exists mainly in the form of esters. Acetic acid exists in animal tissues, excreta and blood in the form of free acid. Many microorganisms can ferment different organic compounds into acetic acid.

In households, a dilute solution of acetic acid is often used as a descaling agent. In the food industry, acetic acid is an acidity regulator specified in the food additive list E260. Although decomposed into weak acids in aqueous solution, acetic acid is corrosive and its vapors are irritating to the eyes and nose. Acetic acid, a simple carboxylic acid, is an important chemical reagent. Acetic acid is also used to make cellulose acetate for motion picture film and polyvinyl acetate in wood binders, as well as many synthetic fibers and fabrics.

The acetyl group in acetic acid is the basis of all life in biochemistry. After combining with coenzyme A, it becomes the center of carbohydrate and fat metabolism.

Industrial applications:

1. Acetic acid is a bulk chemical product and one of the most important organic acids.
2. Acetate formed from lower alcohols is an excellent solvent and is widely used in the paint industry. Acetic acid is also a commonly used organic solvent because it dissolves most organics (e.g. oxidation of p-xylene to produce terephthalic acid).
3. Acetic acid can be used in some pickling and polishing solutions, as a buffer for weakly acidic solutions (such as zinc plating, electroless nickel plating), as an additive to semi-bright nickel plating electrolytes, and for passivation of zinc and cadmium. In the solution, it can improve the binding force of the passivation film, and is often used to adjust the pH value of the weakly acidic plating solution.
4. Used in the production of acetate, such as manganese, sodium, lead, aluminum, zinc, cobalt and other metal salts, widely used as catalysts, auxiliary agents in fabric dyeing and leather tanning industries.
5. Acetic acid can also be used as analytical reagent, organic synthesis, pigment synthesis and medicine.

Food use:

In the food industry, acetic acid is used as an acidulant, flavor enhancer and flavoring agent. When making synthetic vinegar, dilute acetic acid to 4-5% with water, and add various flavoring agents. cheap. As a sour agent, it can be used in compound seasoning, vinegar preparation, canned food, jelly, cheese, etc., and it can be used in an appropriate amount according to production needs. It can also be used as a flavor enhancer for koji wine, and the dosage is 0.1-0.3g/kg.
