The residue is then cooled and acidified with dilute hydrochloric acid. The toluene layer is separated off, washed with water and distilled. Toluene and other low-boiling fractions first distil over and finally pure diethyl phenylmalonate is obtained boiling at 165-166°C, under 20 mm. pressure and having m.p. 16 °C. The yield is 85% of the theoretical.
