The current range of use of sodium acetate is relatively extensive, although it belongs to chemical substances, in different industries can see its figure, generally in the use of its addition to pay attention to the amount of control, so that it can make it in different use of the environment to play its due use effect, the following to give you a specific introduction to its use.
1, used in the printing and dyeing industry: dyeing with it to neutralize the acid to adjust the PH value; Aniline black anti-dye printing is used as neutralizing agent for Naftol dye color solution, as anti-brittleness treatment agent for vulcanized black cloth, etc.
2. In pharmaceutical preparations: organic synthesis in the manufacture of alkaline agents, thyroxine, cystine and sodium meiodopyronic acid: acetylation supplement, cinnamic acid, benzyl acetate, etc.
3, in the pigment industry: used for direct blue reactive dyes, lake pigment acid storage, Shilin blue manufacturing. Other raw materials such as tanning leather, fixing agents for photographic X-ray negatives and electroplating.
4. As a buffer for seasoning, it can alleviate bad odor and prevent discoloration, and has certain anti-mildew effect. Can also be used as seasoning sauce, sauerkraut, mayonnaise, fish cake, sausage, bread, sticky cake and other sour agent. Mixed with methyl cellulose, phosphate, etc., for the preservation of sausage, bread, sticky cake, etc.
Sodium acetate as a chemical substance, want to make it play more advantages, it is necessary to carry out a series of chemical reaction treatment, such as heating treatment, when the heating will change the substance, generate the substance we need, of course, this process is required to do some knowledge, let’s introduce it to you.
1, during the heating process, hydrolysis will occur, and the products of hydrolysis will be NAOH and acetic acid;
2, the NAOH obtained is actually a high-energy substance with strong activity;
3, assuming that NAOH is generated, the generated NAOH will still react with acetic acid to become NAAC, because the substance always changes from high activity to low activity;
4, when heating, it does decompose part of NAOH and acetic acid, you just say heating this solution, and do not mention the temperature.
5, at a certain temperature, acetic acid is a volatile acid, acetic acid volatilization, hydrolysis of NAOH can not volatilize, can only remain in the solution.
Sodium acetate is widely used in chemical industry, iron and steel, metallurgy, coal washing, coking, printing and dyeing, pharmaceutical, chemical preparations, industrial catalysts, preservative preservative, coal chemical industry and other industrial sewage and urban sewage plants.
Usage method
When the dosage of sodium acetate is 30mg/L, the rate of phosphorus release in the anaerobic section, phosphorus absorption in the aerobic section and nitrogen removal in the anoxic section is large. The optimal dosage is more stable and reliable according to the operation of the system through a small experiment.
