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。
Glycerin copper is a dark blue complex salt that can be used as an analytical reagent for aldehydes and reducing sugars. Compared with Fehling reagent, it has some special advantages such as darker color, high sensitivity to reducing sugar and wakefulness And the reaction faster when heated alone is also more stable. Glycerol copper is much cheaper than Fehling reagent, so it is used as a reagent for the identification of aldehydes and reducing sugars and for the quantitative analysis of reducing sugars. Method for preparing glycerol: A liquid - 34.64 Crystalline copper sulfate dissolved in Distilled water, dubbed 500 ml; B liquid - 60 grams of sodium hydroxide and 20 ml of glycerol dissolved in distilled water, dubbed 500 ml Pro before use to take the capacity of the two liquid mixture can be.
