摘要
采用无毒的二甲基亚砜为溶剂,替代行业标准中的有毒、恶臭的吡啶溶剂测定PTA酸值。进行了方法精密度试验与原方法测定结果比较并确定了测定条件。结果准确,方法更加科学、环保。
Non-toxic solvent dimethyl sulfoxide reagent has been used to displace the toxic odorous-pyridine solvent that is adopted in the industry standard to determine PTA＇s acid value.The precision test of the method is carried out,the determination results are compared with the original method,the test conditions are determined.The results are accurate and the method is more scientific and good to environmental protection.
