Properties Of Sodium Acetate

The sodium salt of acetic acid is sodium acetate as known. It is a white or colorless crystalline compound. Most of you must have read name as “diacetate salt and vinegar taste of potato chips on the label, since it is a widespread use of flavoring agents, so that the chip. Sodium acetate, as a food preservative, can also be used in the manufacture of textile and cosmetics.

Industrial manufacturing: the use of glacial acetic acid and sodium hydroxide: CH 3 COOH + sodium hydroxide → sodium acetate + H2O
Sodium acetate can cause respiratory irritation. Excess sodium acetate inhalation causes coughing, sore throat, difficulty breathing and chest pain. Contact with skin or eyes can cause redness of the skin or eyes, irritation and pain.
When a mixture of sodium acetate, acetic acid (vinegar), Sodium Diacetate generated. Sodium diacetate help to improve the flavor of food, but also can be used as food preservatives. It helps to inhibit the growth of harmful bacteria. It was added to the tomato sauce and chips of various types. It helps cancel smelling vinegar and good flavor food. It helps to maintain the desired pH value in certain foods. It is also needed for the purification of the glucose. Sodium acetate medicinal purposes is also very important. It is a form of elemental sodium, and sodium acetate, intravenous administration, and can manage the level of hyponatremia. It can also be used in some other form in the kidney dialysis. These days, the sodium acetate used in wastewater treatment, in place of methanol.
The compound sodium acetate has some unique properties. It maintains a constant pH value of the solution, and therefore is used as a buffer of the biochemical processes (wherein the pH of the solution to determine the chemical reaction). It is used as a buffer in the oil production and drilling mud. It can also acts as a buffer plating. In the textile industry, it is used to neutralize the sulfuric acid. It is a light-sensitive compound (photoresist), and it is used in the textile and leather industries aniline dyes, when used in the manufacturing process.
The injection of sodium acetate is used for the treatment of the imbalance of the electrolyte (sodium). Sodium acetate trihydrate as a diuretic. Sodium acetate can also be used to enhance the flavor of meat and poultry. It is used in the heating pad is reusable, because it releases heat when its crystal. Therefore, sodium acetate is used in various ways, in all industries, because it demonstrated the useful features and is very easy to obtain.
The use of sodium acetate in the textile industry to help create long-lasting fabric. It is used as the staining action of the mordant. Promote the rapid penetration of more uniform tan leather industry. It is necessary, as well as in the production process of the rubber. It can be used as a flame retardant elastomer industry. Sodium Diacetate is present in the various soap and cosmetics, as it can in the products and components. It requires that the organic compound in the manufacturing process, such as dyes, pigments, cinnamic acid, and some drugs.
