Sodium adipate is a chemical compound from the group of carboxylic acid salts and the sodium salt of adipic acid .
Manufacturing
Sodium adipate can be prepared by reaction of adipic acid with sodium carbonate can be produced.
The neutralization of sodium hydroxide solution with an ethanolic solution of adipic acid also yields sodium adipate.
properties
Sodium adipate is a colorless solid that is easily soluble in water. It crystallizes as a hemihydrate in shiny, slightly hygroscopic leaflets. The enthalpy of solution of sodium adipate at 298.15 K is 15.70 kJ mol −1 . The electrolysis of an aqueous solution of sodium adipate produces cyclobutane .
use
Sodium adipate is used as a food additive as a complexing agent and acid regulator . It is also used as a stabilizer for PVC . Barium adipate can be produced by precipitation of a hot barium chloride solution with sodium adipate .
