In the aqueous solution of sodium hydroxide,benzoylformic acid can coordinate with 2,4-dinitrophenylhydrazine to form a complex which has maximum absorption at 458 nm.Thus the content of benzoylformic acid can be quantitatively determined.

在氢氧化钠溶液中，苯乙酮酸和2，4-二硝基苯肼形成一种红棕色的溶液，该溶液在458 nm处有最大吸收，据此可以快速分析混合物中苯乙酮酸的含量。

In this experiment we use the alcohol to replace the Fumaric acid and using the NaOH and HCl to control the pH number.

而本实验就是以过锰酸钾加入酒精以代替过去使用的反丁烯二酸并以HCl及NaOH来调控其酸碱值并比较其反应后的各种性质。

Compared to the control animals, the rats treated with AC showed increased levels of citrate, 2-oxoglutarate and cis -aconitate, and decreased levels of hippurate and phenylacetylglycine in the urine. Such metabolic changes may have reflected, respectively, the changes in body energy metabolism and in the metabolism of intestinal flora in response to AC treatment.

结果表明灌胃给药后代表能量代谢的柠檬酸，2-酮戊二酸（2-oxoglutarate）和顺乌火酸（ cis -aconitate），反应肠道菌群代谢状况的马尿酸盐和苯乙尿酸出现异常，并且这些变化在给药后0~8 h达到最大，16 h后基本恢复正常。

In the case of n-propyl alcohol addition, the molar percent of unsaturated eicosly acids increased, unsaturated octadecyl acids reduced.

在添加正丙醇后，膜脂中不饱和二十酸的摩尔百分含量增加，不饱和十八酸的摩尔百分含量下降。

Mono-and diglycerides contribute to shortening performance and act as staling inhibitors in bakery produces.

甘油单酸和甘油二酸在焙烤制品中赋予制品以松脆的性能，并起着抗老化剂的作用。

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.

剩余物冷却然后用稀盐酸酸化，分理出甲苯层，用水洗涤，然后蒸馏，甲苯和其他低沸点馏分先被蒸馏出来，最后获得20毫米压力下沸点为165-166摄氏度的二乙基苯基丙二酸酯，其熔点为16摄氏度，理论收率为85%。
