Dissolve the residue in 8 ml of toluene R. Filter through a membrane filter (45 μm), rinse the flask and the filter with toluene R and dilute to 10.0 ml with the same solvent.

残留物用8ml甲苯溶解，并用滤膜（45um）过滤，用甲苯冲洗蒸发瓶和过滤器，并稀释到10ml

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.
