Cupric glycerine is a deep blue colored complex salt. It may be used as an analytical reagent for aldehydes and reducing sugars. It possesses certain advantages over Fehling’s reagent in that: its color is more deep, its reaction with aldehydes and reducing sugars exhibits higher sensitivity and is faster, and it is more stable on heating. Cupric glycerine is also much cheaper than Fehling’s reagent. All these properties make it a good substitute for Febling’s reagent in the qualitative analysis of aldehydes...

Cupric glycerine is a deep blue colored complex salt. It may be used as an analytical reagent for aldehydes and reducing sugars. It possesses certain advantages over Fehling’s reagent in that: its color is more deep, its reaction with aldehydes and reducing sugars exhibits higher sensitivity and is faster, and it is more stable on heating. Cupric glycerine is also much cheaper than Fehling’s reagent. All these properties make it a good substitute for Febling’s reagent in the qualitative analysis of aldehydes and both qualitative and quantitative analysis of reducing sugars. Preparation of Cupric glycerine reagent: solution A—34. 64 g. Of CuSO_4·5H_2O dissolved in 500 ml. of distilled water, solution B—60 g. of NaOH and 20 ml. glycerine dissolved in 500 ml. of distilled water. Mix equal volumes of the two solutions before use.

甘油铜是一种深蓝色的络盐,可用为醛类和还原醣的分析试剂,它与Fehling试剂相比较,有其特殊的优点,例如:颜色较深,与还原醣和醒作用时灵敏度高且反应较快单独加热时也较稳定等。甘油铜的价值比Fehling试剂便宜的多,所以用来作醛类和还原醣的鉴定及还原醣的定量分析是值得推广使用的试剂,甘油的制备方法:甲液——34.64结晶硫酸铜溶于蒸溜水,配成500毫升;乙液——60克氢氧化钠和20毫升甘油溶于蒸溜水,配成500毫升临用前取等容量的二液混合即可。

This paper reports the light absorption (between 400--800 mμ) of pyrocate-chol-ferric iron solutions in the range of pH 2--12, and the complexes found bymeans of Job's continuous variation method with spectrophotometer (Unicam,S. P. 500). It is found that there are five complexes in the solutions studied,among which two (I, III) have not yet been reported previously. The resultsare summaried as follows: In solutions of pH intermediate those given above, there are mixtures of thetwo adjacent complexes. For example, in solutions of pH 2.5--3.5 two com-plexes, I and II, exist side by side. The differences between complexes III andV probably lie in differences in electrical charge and (or) structure of theanions. The properties of three known complexes (II, IV, V) confirm those foundby previous authors with slight variations in pH ranges. Fluoride ions can not bleach the color formed in solutions containing ferricions and pyrocatechol of pH 4.2--10. In other words, these complexes are morestable than ferricfluoride complex. Solutions of pH 2--4 do fade as fluoridesolutions are added. However, these colors change gradually with time and isnever so stable as other known reagents for fluoride determination, such asferron-ferric or resacetophenone-ferric reagents. The sensitivity of thepresent reagent towards fluoride is also inferior to that of the reagents justmentioned.
