摘要
本文对液态甲基四氢苯二甲酸酐的游离酸含量分析方法进行了讨论,对比分析了间接方法和直接方法的优缺点,认为用直接电位滴定法测定甲基四氢苯二甲酸酐中游离酸含量,精确度高、重视性好、操作简便快速,适合工业生产要求。
The determining method of free acid in methyl tetrahydrophthalic anhydride (MTHPA) was discussed in this paper. The direct potentiometric titration was compared with indircet determining method and show that the former was better than the latter, its deviation measured was smaller, its repeatability was better, its operation was quicker and simpler and was suitable for the requirement of industrial production.
