巴比妥、苯巴比妥的含量测定,中国药典(1977年版二部)采用银量法。本文采用非水催化温度滴定法,即用氢氧化钾异丙醇液作滴定剂,以丙烯腈作单体,用1/10刻度50℃温度计观察滴定温度变化指示滴定终点,对巴比妥、苯巴比妥原料药及片剂进行了含量测定,并将结果与中国药典(1977年版二部)所载方法测定结果作了比较。仪器与试剂 ZD-2型自动滴定仪(上海分析仪器厂);
Barbiturate, phenobarbital content determination, Chinese Pharmacopoeia (1977 edition two) using the silver method. In this paper, non-aqueous catalytic temperature titration, that is, potassium hydroxide isopropanol as a titrant to acrylonitrile as a monomer, with a 1/10 scale 50 ℃ thermometer titration temperature changes observed end point titration, barbiturate, Phenobarbital APIs and tablets were determined, and the results were compared with the results of the method described in the Chinese Pharmacopoeia (1977 edition).
