Acetic Acid 64-19-7

Mainly used for the preparation of acetic anhydride, vinyl acetate, acetate esters, metal acetates, chloroacetic acid, cellulose acetate, etc., and also serves as a solvent

Used in the synthesis of vinyl acetate, cellulose acetate, acetate esters, metal acetates, and halogenated acetic acids, it is also an important raw material for pharmaceuticals, dyes, pesticides, and organic synthesis

Commonly used as an analytical reagent, general-purpose solvent, non-aqueous titration solvent, and chromatographic reagent. It is also used in organic synthesis. Used as an acidulant, it can be used in compound seasonings, vinegar, canned foods, jellies, and cheeses, with usage adjusted according to production needs. It can also be used as a flavoring agent in aromatic wines, with a usage rate of 0.1–0.3 g/kg.

Acetic acid is a bulk chemical product and one of the most important organic acids. It is primarily used in the production of vinyl acetate, acetic anhydride, acetate esters, and cellulose acetate. Polyvinyl acetate can be made into films and adhesives and is also a raw material for synthetic fibers such as viscose. Acetate cellulose can be used to manufacture artificial silk and motion picture film. Acetates formed from lower alcohols are excellent solvents and are widely used in the paint industry. Acetic acid is an excellent solvent for oxidation reactions (e.g., for the oxidation of para-xylene to produce terephthalic acid).

Acetic acid is an important raw material in the organic synthesis industry, used to synthesize acetic anhydride, diethyl malonate, ethyl acetate, halogenated acetic acids, etc., and can also be used to manufacture drugs such as aspirin and pesticides like 2,4-D. It is also used in the production of acetate salts, such as salts of manganese, sodium, lead, aluminum, zinc, and cobalt, which are widely used as catalysts, auxiliaries in textile dyeing, and leather tanning industries. For example, aluminum acetate is a mordant, a disinfectant, and an astringent in medicine; lead acetate is used as lead white in paint colors; and lead tetraacetate is an organic synthesis reagent.

It can oxidize 1,2-diols into aldehydes or ketones; sodium acetate and potassium acetate are widely used as buffers in biochemistry. In the food industry, acetic acid is used as an acidifier, flavor enhancer, and flavoring agent. When manufacturing synthetic vinegar, acetic acid is diluted with water to a concentration of 4-5%, and various flavorings are added. The flavor is similar to that of traditionally brewed vinegar, but the production time is shorter and the cost is lower. Acetic acid has strong corrosive properties.

It can cause skin irritation and blistering. It is classified as a secondary organic acid corrosive substance. Its primary uses include the preparation of acetic anhydride, vinyl acetate, acetate esters, metal acetates, chloroacetic acid, and cellulose acetate, which are used in the production of ethyl acetate, food flavorings, and wine flavorings. It is also used as an analytical reagent, solvent, and cleaning agent, and is a commonly used organic acid. Applications include analysis, solvents, organic synthesis, and the preparation of buffers. It is also used as a catalyst for dyeing solutions and as an auxiliary material.
