Summary
A method is described for preparing the sodium salt of β-oxybutyric acid from acetoacetic ester. The acetoacetic ester is reduced by aluminium amalgam in moist sulphuric acid, and the β-oxybutyric acid thus obtained is then saponified to form the sodium salt of β-oxybutyric acid. The yield is approximately 30%.
