Introduce: Acetic acid (AcOH) is a weak carboxylic acid, with the typical properties of carboxylic acid, and some metals, metal oxides and hydroxides react to form salts, many acetates have important uses, for example, lead tetraacetate is an important oxidant, basic iron acetate [Fe(C2H3OO) 6OH(OOCCH3)2] and [Fe3(C2H3OO)6(OH)2(OOCCH3)], lead acetate is used as mordant, ferrous acetate is used for printing. Acetic acid reacts with alcohol for esterification; It can also undergo esterification reaction with unsaturated hydrocarbons under the action of catalyst; α-Hydrogen can be replaced by halogens; and formaldehyde under the action of catalyst, into Chemicalbook for alkaldehyde condensation; When nitric acid undergoes nitrification reaction in acetic acid, the nitrification rate can be improved; Reacts with benzoyl chloride to form acetyl chloride and benzoic acid. Acetic acid can produce a variety of derivatives with important uses, such as methyl acetate, ethyl ester, propyl ester, butyl ester, etc., and is an excellent solvent for the paint and paint industry. The cellulose acetate produced by the reaction of acetic anhydride and cellulose can be used in the manufacture of film, spray paint and various plastic products. Monochloroacetic acid can be used to prepare carboxymethylcellulose. Vinyl acetate produced by acetic acid and acetylene is an important raw material for the synthesis of drugs, dyes, spices, and an important solvent for the treatment of rubber, and acetic acid has an important position in industrial production and organic synthesis.
Stockpile: Use glass bottles, acid jars, polyethylene bottles or polyethylene-lined metal drums to keep dry, and the storage temperature should be kept above the freezing point. Avoid rupture of large bottles, acid jars or Chemicalbook glass containers. Glacial acetic acid containers prevent mechanical damage. It is best to store it in the attached warehouse. Separate from oxidants and avoid storage near combustibles.
Uses:
Commonly used analytical reagents, widely used for neutralization or acidification. Non-aqueous titration solvents, preparation of buffer solutions, organic synthesis. Manufacture of pigments, drugs, acetate fibers, acetyl compounds, etc. It is also used to dissolve phosphorus, sulfur, hydrohalic acid, etc. As a sour agent, it can be used as a compound seasoning, prepare vinegar, canned food, jelly and cheese, and use it in appropriate amounts according to production needs. It can also be used as a flavor enhancer for koji liquor, and the amount used is 0.1-0.3g/kg. Used as a solvent in the manufacture of rubber, plastics, dyes, etc. It is also used as a raw material for the manufacture of vinyl acetate, cellulose acetate, menthyl acetate, photographic drugs, pharmaceuticals, pesticides and other organic synthesis.
Commonly used analytical reagents. Universal solvents and non-aqueous titration solvents. Used in the manufacture of acetate, cellulose acetate, medicine, pigments, esters, plastics, spices, etc.
PH value regulator. It can be used for the preparation of ethyl acetate, the preparation of fibers, paints, adhesives, copolymer resins, etc., the preparation of acetic anhydride, chloroacetic acid, glycolic acid and industrial pickling.
Can be used for industrial pickling. For the preparation of fibers, coatings, adhesives, copolymer resins, etc.
It is an important organic chemical raw material, which can produce a variety of organic chemical products. The pharmaceutical industry is used to prepare a variety of medicines, the dye industry is used to manufacture a variety of dyes, and the synthetic materials industry is used to synthesize a variety of polymer materials, which is an important organic chemical intermediate. In addition, it is also used as industrial solvents, leather tanning agents, rubber latex coagulants, dye aids, artificial fragrances, chemical reagents, etc., and also used as acidulants, flavor enhancers, etc.
Acetic acid can be used in some pickling and polishing solutions, in weak acidic solutions as buffers (such as galvanizing, electroless nickel plating), in semi-bright nickel plating electrolyte as additives, in zinc, cadmium passivation solution can improve the adhesion of the passivation film, and commonly used to adjust the pH of weak acid plating solution, can also be used as a solvent for some organic additives (such as coumarin).
Commonly used analytical reagents, general solvents and non-aqueous titration solvents, organic synthesis, synthesis of pigments and pharmaceuticals.
Used in the manufacture of acetate, cellulose acetate, medicine, pigments, esters, plastics, spices, etc.
