目的:建立盐酸普罗帕酮非水滴定中革除汞盐的含量测定方法。方法:采用以无水甲酸-醋酐(1∶50)为溶剂的高氯酸电位滴定法。结果:革除汞盐后方法含量测定结果与原方法结果基本一致,可以代替原方法。结论:方法简便、易行,可用于盐酸普洛帕酮的质量控制。
Objective: To establish a method for determining the content of mercury salt in propafenone hydrochloride non-aqueous titration. Methods: Perchloric acid potentiometric titration with anhydrous formic acid - acetic anhydride (1:50) as solvent. Results: After removing mercury salts, the content of the method was basically the same as the original method, which could replace the original method. Conclusion: The method is simple and easy to perform and can be used for the quality control of plo- laprenone hydrochloride.
