1, used in the manufacture of acetate, cellulose acetate, medicine, pigments, esters, plastics, spices and so on.
Second, used for the synthesis of vinyl acetate, acetate fiber, acetate, metal acetate and halogenated acetic acid, is also an important raw material for pharmaceutical, dyes, pesticides and organic synthesis
3. Used as analytical reagent, solvent and immersion agent
4, for the production of ethyl acetate, edible spices, wine spices, etc
5, commonly used as analytical reagents, general solvents and non-aqueous titration solvents and chromatographic analysis reagents, but also used in organic synthesis
6, as a sour agent, can be used for compound seasonings, preparation of vinegar, canned, jelly and cheese, according to the production needs of appropriate use. It can also compose the aroma enhancer of incense wine, the amount of use is 0.1 ~ 0.3g/kg.
Acetic acid is a bulk chemical product and one of the most important organic acids. It is mainly used in the production of ethylene acetate, acetic anhydride, acetate and cellulose acetate. Polyvinyl acetate can be made into films and adhesives, and is also the raw material of synthetic fiber Vinylon. Cellulose acetate is used to make rayon and motion picture film. Acetate formed by lower alcohols is an excellent solvent and is widely used in paint industry. Acetic acid is a good solvent for oxidation reactions (e.g. for the production of terephthalic acid by the oxidation of p-xylene). Acetic acid is an important raw material in the organic synthesis industry, which is used to synthesize acetic anhydride, diethyl malonate, ethyl acetoacetate, halogenated acetic acid, etc., and can also manufacture drugs such as aspirin and pesticide 2, 4-drops. It is also used in the production of acetate salts, such as manganese, sodium, lead, aluminum, zinc, cobalt and other metal salts, and is widely used as catalysts, textile dyeing and additives in the leather tanning industry. For example, aluminum acetate is a mordant, disinfectant and sword catcher for medicine; Lead acetate is paint color lead white; Lead tetraacetate is an organic synthesis reagent. 1, 2-diol can be oxidized into aldehydes or ketones; Sodium acetate and potassium acetate are widely used buffers in biochemistry. In the food industry, acetic acid is used as an acidifier, flavoring agent and flavoring agent. When making synthetic vinegar, the acetic acid is diluted with water to 4-5 concentration, and various flavoring agents are added. The flavor is similar to that of alcohol, and the manufacturing time is short and the price is cheap. Acetic acid is highly corrosive. Irritation and pain to the skin, blisters. It is a secondary organic acid corroded item.
