Anhydrous sodium acetate is an organic substance with the molecular formula C2H3NaO2. It is a white powder that is hygroscopic, easily soluble in water, and soluble in ethanol.
Anhydrous sodium acetate has a variety of uses, including:
1. Organic synthesis: As an esterification agent, it is used to synthesize various chemical products, such as furan, acrylic acid, acetate and chloroacetic acid.
2. Pharmaceuticals and medicine: used as medicine, printing and dyeing mordant, buffering agent, chemical reagent, etc.
3. Food industry: As a buffering agent for seasonings, it is used to alleviate bad odors, prevent discoloration, and improve flavor. The use of 0.1%-0.3% anhydrous sodium acetate in minced fish products and bread has a certain anti-fungal effect. In addition, it is also used as a sour agent for sauces, sauerkraut, mayonnaise, fish cakes, sausages, bread, sticky cakes, etc. Mixed with methylcellulose, phosphate, etc., it is used to improve the preservation of sausages, bread, sticky cakes, etc.
4. Electroplating and rubber industry: used as an anti-scorch agent for the coking of sulfur-regulated chloroprene rubber and a cross-linking agent for animal glue.
5. Electroplating application: Although it is not a necessary component, it can be used to add tin in alkaline electroplating and has no obvious impact on the plating and electroplating process. Sodium acetate is commonly used as a buffer, such as in acid zinc plating, alkaline tin plating and electroless nickel plating.
6. Analysis and industrial application: used to determine complex stabilizers for lead, zinc, aluminum, iron, cobalt, antimony, nickel, tin and other metals, as well as acetylation auxiliaries, desiccants, etc.
To sum up, anhydrous sodium acetate is a multifunctional chemical that is widely used in many fields such as organic synthesis, medicine, food, electroplating and rubber.
