Sodium acetate, also known as sodium acetate, is an organic substance with a molecular formula of CH3COONa and a molecular weight of 82.03. Sodium acetate trihydrate is a white crystal with a relative density of 1.45 and a melting point of 58°C. When weathered in dry air, it loses crystal water at 120°C and decomposes at higher temperatures. Anhydrous sodium acetate is a colorless transparent crystal with a melting point of 58°C. 324ºC. Easily soluble in water, it can be used as buffer, mordant, determination of lead, copper, nickel and iron, medium preparation, organic synthesis, film printing, etc.
1. Determination of lead, zinc, aluminum, iron, cobalt, antimony, nickel and tin. Complex stabilizer. Acetylation auxiliaries, buffers, desiccants, mordants
2. Used to determine lead, zinc, aluminum, iron, cobalt, antimony, nickel, and tin. Used as esterification agent in organic synthesis, photography, pharmaceuticals, medicine, printing and dyeing mordants, buffers, chemical reagents, meat preservatives, pigments, tanning, etc.
3. Used as buffering agent, flavoring agent, flavor enhancer and pH adjuster. As a buffering agent for flavoring agents, 0.1%-0.3% can be used to alleviate bad odors and prevent discoloration to improve flavor. It has a certain anti-mold effect, such as using 0.1%-0.3% in minced fish products and bread. It can also be used as a sour agent for sauces, sauerkraut, mayonnaise, fish cakes, sausages, bread, sticky cakes, etc. Mixed with methylcellulose, phosphate, etc., used to improve the preservation of sausages, bread, sticky cakes, etc.
4. Used as an anti-scorch agent for sulfur-regulated chloroprene rubber coking, the dosage is generally 0.5 parts by mass. It can also be used as a cross-linking agent for animal glue.
5. This product can be used to add tin in alkaline electroplating, but it has no obvious impact on the plating and electroplating process and is not a necessary ingredient. Sodium acetate is commonly used as a buffer, such as in acid zinc plating, alkaline tin plating and electroless nickel plating.
