Benedict's solution

本尼迪克特的试剂

Benedict's reagent

本尼迪克特的试剂是以美国化学家斯坦利·罗斯特本尼迪克特命名的化学试剂。 本尼迪克特的试剂用作还原糖存在的试验。 这包括所有单糖和许多二糖,包括乳糖和麦芽糖。 更为普遍的是,本尼迪克特的测试将检测醛和α-羟基酮的存在,包括在某些酮糖中发生的那些酮。 因此,尽管酮糖果糖不是严格的还原糖,但是它是α-羟基酮,并且由于其在试剂中被碱转化成醛糖葡萄糖和甘露糖而得到阳性试验。 本尼迪克特试剂的阳性试验显示为从透明蓝色到砖红色沉淀物的颜色变化。 可以从100g无水碳酸钠,173g柠檬酸钠和17.3g五水合硫酸铜制备1升本尼迪克特试剂。 它经常用于代替Fehling的解决方案。 本尼迪克特的试剂含有蓝铜离子,其被还原成铜离子。 它们以不溶于水的红色氧化铜沉淀。 Benedict's reagent is a chemical reagent named after an American chemist, Stanley Rossiter Benedict. Benedict's reagent is used as a test for the presence of reducing sugars. This includes all monosaccharides and many disaccharides, including lactose and maltose. Even more generally, Benedict's test will detect the presence of aldehydes, and alpha-hydroxy-ketones, including those that occur in certain ketoses. Thus, although the ketose fructose is not strictly a reducing sugar, it is an alpha-hydroxy-ketone, and gives a positive test because it is converted to the aldoses glucose and mannose by the base in the reagent. A positive test with Benedict's reagent is shown by a colour change from clear blue to a brick-red precipitate. One litre of Benedict's reagent can be prepared from 100 g of anhydrous sodium carbonate, 173 g of sodium citrate and 17.3 g of copper sulfate pentahydrate. It is often used in place of Fehling's solution. Benedict's reagent contains blue copper ions which are reduced to copper ions. These are precipitated as red copper oxide which is insoluble in water.
