Glacial acetic acid is widely found in nature. It is an organic compound

and a typical fatty acid. It is recognized as the source of sour taste and

pungent odor in vinegar. In the home, dilute acetic acid solution is often

used as a scale remover. In the food industry, acetic acid is a regulated

acidity regulator in the food additive list E260.

Glacial acetic acid is one of the most important organic acid, mainly used for vinyl acetate, acetic anhydride, cellulose acetate, acetate and metal acetic acid salt, also used as pesticide, medicine and dye industries of solvent and raw materials, in photographic drug manufacturing, fabric printing and dyeing, and has wide applications in rubber industry. Glacial acetic acid is one of

the important organic chemical raw materials, it is in an important position in the organic chemistry industry. Acetic acid is widely used in synthetic fiber,

coating, medicine, agricultural chemicals, food additives, textile and other

industries, is an important part of national economy.

Glacial acetic acid is divided into industrial and edible types according to its USES. Edible glacial acetic acid can be used as acid flavor agent, flavor

enhancer, and synthetic vinegar can be produced. Its flavor and brewed

vinegar are similar, often used in tomato ketchup, mayonnaise, drunken

MiTang sauce, pickles, cheese, sugar, food products, etc. When using

appropriate dilution, can also be used to produce tomatoes, asparagus, baby food, canned sardines, squid, etc, and pickled cucumber, gravy soup, cold

drinks, cheese acid method used in food spices, dilution, can produce soft

drinks, cold drinks, candy, baked goods, pudding, adhesive medium sugar,

spices, etc. As an acid flavor agent, it can be used to mix drinks and cans.

Washing usually use glacial acetic acid, concentration of 28%, 56%, 99%. If buy is glacial acetic acid, add the 28 cc glacial acetic acid to the 72 cc water, can get 28% acetic acid. More common is that it is sold at the concentration of 56%, this is because the concentration of acetic acid as long as to add the same amount of water, can get 28% acetic acid. The concentration gets 28% of acetic acid can be damaged by acetic acid and denar fibril arnon. Oxalic acid is one of the strong acids in organic acids. In the acid solution of potassium permanganate, oxalic acid is easy to be oxidized into carbon dioxide and water. Oxalic acid can neutralize with alkali to form oxalate. Like ammonia neutralizes acid, 28% acetic acid can also neutralize alkaline. Alkali can also lead to change color. With acid (e.g., 28% acetic acid) can recover the discoloration. This acid is also used to reduce the complex tannins, tea, coffee, fruit, yellow stains caused by soft drink and beer. When remove these stains, 28% acetic acid in water and neutral lubricant, available to the extent.
