1.Sodium acetate is also known as sodium acetate. Colorless, odorless, transparent monoclinic columnar crystal, or white crystalline powder.

2.In food production, it is used as a buffer for seasoning and a meat preservative. Control the sticky phenomenon caused by fungi in bread production and use it in grain preservation with high water content; This product can also be used as textile printing chemicalbook dyeing auxiliary (mordant), buffer for photographic industry, chemical reagent and pharmaceutical intermediate; It can also be used as raw materials for the synthesis of organic chemical products, such as furan acrylic acid, acetate esters, chloroacetic acid, acetic anhydride and cinnamic acid.

3.Colorless and odorless crystal, which can be weathered and combustible in air. Soluble in water and ether, slightly soluble in ethanol. The melting point of sodium acetate trihydrate is 58 ℃, the relative density is chemicalbook1.45, and the spontaneous combustion point is 607.2 ℃. Remove 3 molecules of water at 123 ℃. The melting point of anhydrous sodium acetate is 324 ℃, and the relative density is 1.528.

Application

1.Anhydrous sodium acetate can be used in organic synthesis of esterification agents, photographic drugs, medicine, printing and dyeing mordants, buffers, chemical reagents, meat preservatives, pigments and many other aspects, and can be used to produce various chemical products, such as furan propylene chemicalbook enoic acid, acetate and chloroacetic acid. As a buffer for seasoning, this product can prevent discoloration and has a certain anti mildew effect. It can also be used as a sour agent for seasoning sauce, pickled cabbage, mayonnaise, fish cake, sausage, bread, rice cake, etc.

2.Sodium acetate mainly plays a role in adjusting the pH value of sewage in sewage treatment. Sodium acetate is an alkaline chemical, which can be hydrolyzed in water to form Oh negative ions, which can neutralize chemicalbook and acidic ions in water, such as h+, nh4+. The hydrolysis reaction formula of sodium acetate is: ch3coo-+h2o= reversible =ch3cooh+oh-.
