Properties: Colorless and odorless crystals, can be weathered in air. Soluble in water and ether, slightly soluble in ethanol. The melting point of sodium acetate trihydrate is 58°C, relative density 1.45, auto-ignition point 607.2°C. Loses 3 molecules of water at 123°C. The melting point of anhydrous sodium acetate is 324°C, relative density 1.528.

Uses: Used as an esterifying agent in organic synthesis and in many areas such as photographic chemicals, pharmaceuticals, dyeing mordants, buffers, chemical reagents, meat preservation, pigments, tanning, etc. Can be used to produce various chemical products, such as furan acrylic acid, acetate esters, and chloroacetic acid. As a buffer in condiments, it can mitigate undesirable odors and prevent discoloration, with certain anti-mold effects. Also used as an acidulant in seasoning sauces, pickles, mayonnaise, fish paste, sausages, bread, sticky rice cakes, etc. Mixed with methyl cellulose, phosphates, etc., to improve the shelf life of sausages, bread, sticky rice cakes, etc. Used as a general analytical reagent, mordant, buffer, and also in dye synthesis and film processing. Used in pharmaceuticals, dyeing, and organic synthesis as a mordant and buffer, also in the dye and pharmaceutical industries for printing and dyeing, medicine, photography, etc., and also as an esterifying agent and preservative.

Sodium acetate generally exists in the form of sodium acetate trihydrate with three water molecules. Sodium acetate trihydrate is colorless transparent or white granular crystals, which can be weathered in air. Easily soluble in water, slightly soluble in ethanol, insoluble in ether. Loses water of crystallization at 123°C. However, it usually has an acetic acid odor when prepared by wet methods. Hydrolyzes in water.

Sodium acetate is mainly used as a dyeing auxiliary, meat preservative, and raw material for producing acetic anhydride. Used in electronics, instrumentation, and metallurgical industries. Also used in chemical reagents, electroplating, cement grinding aids, water treatment, and other fields.

1. Determination of lead, zinc, aluminum, iron, cobalt, antimony, nickel, and tin. Complex stabilizer. Auxiliary agent for acetylation, buffer, desiccant, mordant.

2. Used for the determination of lead, zinc, aluminum, iron, cobalt, antimony, nickel, and tin. Used as an esterifying agent in organic synthesis and in many areas such as photographic chemicals, pharmaceuticals, dyeing mordants, buffers, chemical reagents, meat preservation, pigments, tanning, etc.

3. Used as a buffer, flavoring agent, flavor enhancer, and pH adjuster. As a buffer in condiments, it can mitigate undesirable odors and prevent discoloration; used at 0.1% to 0.3% to improve flavor. Has certain anti-mold effects, such as using 0.1% to 0.3% in fish and meat paste products and bread. Also used as an acidulant in seasoning sauces, pickles, mayonnaise, fish paste, sausages, bread, sticky rice cakes, etc. Mixed with methyl cellulose, phosphates, etc., to improve the shelf life of sausages, bread, sticky rice cakes, etc.

4. Used as an anti-scorching agent for sulfur-regulated chloroprene rubber coking, generally used at 0.5 parts by mass. Also used as a cross-linking agent for animal glue.

5. This product can be used as an additive in alkaline tin electroplating, but it has no significant effect on the plating layer or the electroplating process and is not a necessary component. Sodium acetate is commonly used as a buffer, such as in acidic zinc plating, alkaline tin plating, and chemical nickel plating.
