Glacial acetic acid

Role purpose of glacial acetic acid is one of the most important organic acids. Mainly used for vinyl acetate, acetic anhydride, cellulose acetate, acetate and metal acetate salts, also used as a solvent and raw material pesticide, medicine and dyes and other industries, in manufacturing photographic chemicals, textile dyeing and rubber industries have a wide range purposes. Glacial acetic acid is an important organic chemical raw materials, it is an important position in organic chemistry industry. Acetic acid is widely used in synthetic fibers, coatings, pharmaceuticals, pesticides, food additives, dyeing and other industries, is an important part of national economy. Glacial acetic acid and consumption by end-use is divided into two kinds of industries, consumption of acetic acid can be used as sour agents, flavoring agents. Produce synthetic vinegar. Acetic acid was diluted with water to a concentration of 4-5%, the addition of various flavoring agents to give vinegar. Its flavor is similar with vinegar commonly used in tomato sauces, mayonnaise, rice bran drunk sauce, pickles, cheese, confectionery products. When using the appropriate dilution, but also for the production of tomatoes, asparagus, baby food, sardines, squid and other canned, and pickled cucumber, when meat soups, cold drinks, cheese acid method used in food spices, to be diluted, can be made soft drinks, cold drinks , candy, baked goods, puddings class, plastic medium sugar, spices and the like. As sour agent, it can be used for adjusting drinks, canned food and so on. Acetic acid concentration in the washing normally used were 28%, 56%, 99%. If you buy glacial acetic acid, glacial acetic acid is added to the 28CC 72CC of the water, you can get 28% acetic acid. More commonly, it sold 56% concentration, it is because of this concentration of acetic acid just add the same amount of water, you can get 28% acetic acid. Big concentration of 28% acetic acid can damage the cellulose acetate fiber and Denar child. Oxalic acid is one organic acid in acidic solution of potassium permanganate, oxalic acid is easily oxidized to carbon dioxide and water. Oxalic acid with alkali from the neutralization reaction of oxalate. Acetic acid, too, 28% acetic acid is volatile, volatile after the fabric is neutral; as ammonia can neutralize the acid, as 28% of acetic acid can be neutralized base. Base will lead to discoloration. With an acid (such as 28% acetic acid) to recover the color. This acid is also used to reduce the tannin complexes, tea, coffee, fruit count, soft drinks and beer cause yellow stains. When removing these stains, 28% acetic acid is used after water and neutral lubricant, available to the maximum extent.
