摘要
在用有机热载体劣化程度的监测中,酸值是一项重要的检测项目。文章采用中和滴定法和红外光谱两种方法对有机热载体氧化过程中酸值变化进行对比研究,认为红外光谱中1715cm-1下吸收峰与酸值变化具有相关性。
Acid Number is important testing item for monitoring of In-used heat transfer fluids （HTFs）.The report combined the potentionmetric titration with FTIR to research the change of Acid Number in oxidation process.It was found that Acid Number correlated to the absorbance of 1715 cm-1 in FTIR spectrum.
