Moisture content of all flour fractions was stabilized to about 12 percent before blending. Each soft wheat flour fraction was blended with each hard wheat flour fraction under various blending ratios (20:80, 40:60, and 80:20) and blending times (10, 20, 30, 40, 50, 60, 120, and 180 sec) in a drum mixer.
在混合之前,所有面粉块的水分含量保持在12%,每一种软麦粉块按不同混合比例和混合时间与一定的硬麦粉块混合在一个鼓形混合器中。

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.
