Acetic AcidAs a bulk chemical product, the industrial production methods of acetic acid include fermentation, methylcarbonylation, acetaldehyde oxidation, etc.

The Application for Acetic Acid:

Acetic acid can be used as an organic synthesis raw material, to prepare metal salt catalysts, food seasonings, buffer solutions, etc.

1. Industry

   (1) Acetic acid is a bulk chemical product and one of the most important organic acids. Mainly used for the production of acetic anhydride, acetate, and cellulose acetate. Polyvinyl acetate can be used to make films and adhesives, and is also a raw material for synthetic fiber vinylon. Cellulose acetate can be used to produce synthetic silk and film.

   (2) Acetate formed from lower alcohols are excellent solvents widely used in the paint industry. Because acetic acid dissolves most organic matter, it is also a commonly used organic solvent (such as for the oxidation of xylene to produce terephthalic acid).

   (3) Acetic acid can be used in certain pickling and polishing solutions, as a buffering agent in weakly acidic solutions (such as zinc plating and electroless nickel plating), as an additive in semi bright nickel plating electrolytes, and as a passivating agent in zinc and cadmium passivation solutions to enhance the adhesion of passivation films. It is also commonly used to adjust the pH of weakly acidic plating solutions.

   (4) Used for the production of acetate salts, such as manganese, sodium, lead, aluminum, zinc, cobalt and other metal salts, widely used as catalysts, auxiliaries in fabric dyeing and leather tanning industries; Lead acetate is the color of paint, lead white; Lead tetraacetate is an organic synthesis reagent (such as lead tetraacetate, which can serve as a strong oxidant, provide a source of acetoxy groups, and prepare organic lead compounds).

   (5) Acetic acid can also be used as an analytical reagent in organic synthesis, pigment and drug synthesis.

2. Food

   In the food industry, acetic acid is used as an acidifier, flavoring agent, and flavoring agent. When synthesizing vinegar, acetic acid is diluted with water to 4-5% and various seasonings are added. The flavor is similar to alcohol vinegar, and the manufacturing time is short and the price is cheap. As an acidifier, it can be used for compound seasoning, preparing vinegar, canned food, jelly, and cheese, and used in appropriate amounts according to production needs. It can also be used as a fragrance enhancer for aromatic wine, with a dosage of 0.1-0.3 g/kg.

3. Clinical

   The rectum is a common site for various intestinal diseases, and ordinary colonoscopy is difficult to detect early cancer, small lesions, and other difficult to detect lesions. Therefore, misdiagnosis and missed diagnosis often occur. However, when using magnifying endoscopic technology to confirm whether there is a lesion in the large intestine, spraying a certain concentration of acetic acid on the rectal mucosa can cause the gastric mucosa to turn white and enhance the contour of the gastric antral mucosa, thereby improving the diagnostic effect of gastric mucosal tumors and intestinal metaplasia.

Is acetic acid corrosive？

Acetic acid is corrosive. Acetic acid, also known as acetic acid, with the chemical formula CH3COOH or C2H4O2, is an organic compound. It usually exists in the form of glacial acetic acid in its natural state, and is a colorless, pungent liquid. Acetic acid is a weak acid with strong corrosiveness, which can corrode certain metals such as iron. In addition, acetic acid is flammable and tear jerking, and its vapors have irritating effects on the eyes and nose.
