Sodium acetate undergoes decarboxylation to form methane (CH 4) under forcing conditions (pyrolysis in the presence of sodium hydroxide):a b Hsu, Leh-Yeh; Nordman, C. E. (1983). "Structures of two forms of sodium acetate, Na +.C 2H 3O 2 −". Acta Crystallogr. C. 39 (6): 690–694. doi: 10.1107/S0108270183005946. Sodium acetate is used to mitigate water damage to concrete by acting as a concrete sealant, while also being environmentally benign and cheaper than the commonly used epoxy alternative for sealing concrete against water permeation.

International Chemical Safety Cards. National Institute of Occupational Safety and Health. 2018-09-18. Sodium acetate is also used in heating pads, hand warmers, and hot ice. A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat.

Industrially, sodium acetate trihydrate is prepared by reacting acetic acid with sodium hydroxide using water as the solvent. a b Cameron, T. S.; Mannan, K. M.; Rahman, M. O. (1976). "The crystal structure of sodium acetate trihydrate". Acta Crystallogr. B. 32: 87–90. doi: 10.1107/S0567740876002367. A solution of sodium acetate (a basic salt of acetic acid) and acetic acid can act as a buffer to keep a relatively constant pH level. This is useful especially in biochemical applications where reactions are pH-dependent in a mildly acidic range (pH 4–6). Austen, Ian (2018-06-09). "The Secret Story of Salt and Vinegar Chips: the Canada Letter". The New York Times. ISSN 0362-4331 . Retrieved 2021-11-23.To manufacture anhydrous sodium acetate industrially, the Niacet Process is used. Sodium metal ingots are extruded through a die to form a ribbon of sodium metal, usually under an inert gas atmosphere such as N 2 then immersed in anhydrous acetic acid. Sodium acetate, CH 3COONa, also abbreviated Na O Ac, [8] is the sodium salt of acetic acid. This colorless deliquescent salt has a wide range of uses.

Sodium acetate may be added to food as a seasoning, sometimes in the form of sodium diacetate, a one-to-one complex of sodium acetate and acetic acid, [10] given the E-number E262. It is often used to give potato chips a salt and vinegar flavour, and may be used as a substitute for vinegar itself on potato chips as it doesn't add moisture to the final product. [11] Sodium acetate (anhydrous) is widely used as a shelf-life extending agent and pH control agent. [12] It is safe to eat at low concentration.
