摘要
通过大量实验,研究了溴水氧化醛糖和酮糖的条件、产物和机理.结果表明:在pH=2～3的酸性条件下,溴水能鉴别葡糖糖和果糖;在pH=5～6的近中性条件下或pH=9～10的碱性条件下,溴水不能鉴别葡糖糖和果糖;并且找出了最佳的鉴别方法.
The conditional, product and mechanism of Bormine Water oxidating Aldose and Ketose are discussed in this paper. The results show： in the acid solution which pH is 2～3, Bormina Water can distinguish Glucose and Fructose ;in the nearly neutral solution which pH is 5～6 and in the Alkalescence solution which pH is 9～ 10. Bormina Water can not distinguish Glucose and Fructose ; Further more the best distinguishing method is given.
