Sodium adipate is a chemical compound selected from the group of carboxylic acid salts and the sodium salt of adipic acid.

Production

Sodium adipate may be prepared by reaction of adipic acid with sodium carbonate.

Also, the neutralization of sodium hydroxide with an ethanolic solution of sodium adipate adipic supplies.

Properties

Sodium adipate is a colorless solid which is readily soluble in water. It crystallizes as the hemihydrate in shiny, slightly hygroscopic flakes. The enthalpy of solution of sodium adipate at 298.15 K is 15.70 kJ · mol -1. In the electrolysis of an aqueous solution of sodium adipate produced cyclobutane.

Use

Sodium adipate is used as a food additive as a complexing agent and an acidity regulator. In addition, it is used as a stabilizer of PVC.
