剩余滴定法测定蔗糖八醋酸酯的含量

Determination of Sucrose Octaacetate by Residual Titration

目的建立蔗糖八醋酸酯的含量测定方法。方法采用剩余滴定法,蔗糖八醋酸酯与NaOH反应后,用H2SO4滴定过量的NaOH。结果回收率为100.1%,RSD=0.2%。结论本法简便可行、重复性好,可用于蔗糖八醋酸酯的的质量控制。

Objective To establish a method for the determination of sucrose octaacetate. Methods Residual titration was used, after the reaction of sucrose octaacetate with sodium hydroxide VS, the residual sodium hydroxide VS was titrated with sulfuric acid VS. Results The average recovery was 100.1%, and RSD was 0.2%. Conclusion The method is simple, feasible and reliable. It can be used for the quality control of sucrose octaacetate.
