草酸二甲酯酸值测定方法的讨论与优化

Discussion and optimization of determination method of dimethyl oxalate acid value

通过对比不同溶剂对草酸二甲酯酸值测定的影响,实验结果表明,甲醇为一种合适的溶剂。对比人工手动滴定方法与自动电位滴定仪滴定方法,在准确度和精密度方面,自动电位滴定仪滴定方法均优于人工手动滴定方法,是一种理想的草酸二甲酯酸值测定方法。

By comparing the influence of different solvents on the determination of dimethyl oxalate acid value,the experimental results show that methanol is a suitable solvent.Compared with the manual titration method and the automatic potentiometric titration method,the automatic potentiometric titration method is superior to the manual titration method in accuracy and precision,and is an ideal method for the determination of dimethyl oxalate acid value.
