Uses
In chrome tanning, Sodium acetate (CAS NO.6131-90-4) is used as a pickling agent.It is usually used to impede vulcanization of chloroprene in synthetic rubber production. Sodium acetate is also used to neutralize sulfuric acid waste streams in the textile industry, and as a photoresist while using aniline dyes. It is also a pickling agent in chrome tanning, and it helps to retard vulcanization of chloroprene in synthetic rubber production.
It may decrease the risk of a hangover when be added to alcoholic beverages and may be a seasoning when be added to foods.It may be used in the form of sodium diacetate — a 1:1 complex of sodium aceta
Sodium acetate can be used to form an ester with an alkyl halide such as bromoethane:
H3C-COO-Na+ + Br-CH2-CH3 → H3C-COO-CH2-CH3 + NaBr
In such a reaction, the Sodium acetate is usually complexed with caesium in order to increase the nucleophilicity of the carboxylate group.
Production
Sodium acetate (CAS NO.6131-90-4) is sometimes producted from the reaction of Acetic acid with sodium carbonate, sodium bicarbonate, or sodium hydroxide,which produces aqueous sodium acetate, and water.Carbon dioxide is produced in the reaction with sodium carbonate and bicarbonate, and it leaves the reaction vessel as a gas (unless the reaction vessel is pressurized).
CH3–COOH + Na+[HCO3]– → CH3–COO– Na+ + H2O + CO2
This is the well-known "volcano" reaction between baking soda and vinegar.84 grams of sodium bicarbonate (baking soda) react with 750 ml of 8% vinegar to make 82 g sodium acetate in water. By boiling off most of the water, one can refine either a concentrated solution of sodium acetate or crystals.
Consensus Reports

Safety Profile
When Sodium acetate is heated to decomposition it will emit acrid smoke and irritating fumes.
