摘要
利用乙酸酐、吡啶和浓硫酸混合的乙酰化试剂测定环氧树脂中羟基值含量的方法具有操作简便、滴定终点明显和分析结果误差小等优点。
The hydroxyl value may be determined with an agent obtained by mixing acetic anhydride , pyridine and concentrated sulfuric acid. This method is easy for operation and exhibits a clear end point of titration and a small error in the determination result.
