摘要
提出了一种通过差示扫描量热技术测定双酚A纯度的方法.该方法仅与试样的物理化学特性有关,不需要参考标样.由于直接测定杂质含量,而非纯样本身,实验操作误差对纯度影响大大降低.实验证实,该方法可作为常规双酚A产品质量控制手段.
A method for determining the purity of b isphenol A by differential scanning calorimetry is presented. This method depend s only on the physical-chemical behavior of bisphenol A, and no reference stand ard is necessary. Because the concentration of the contaminants, rather than the pure substance, is measured directly, the effect of experimental error on the p urity of bisphenol A is minimized.It is recommended as a new valuable tool for c ontrolling the quality of bisphenol A products.
