本文研究了以0.01N高氯酸溶液为标准溶液进行有机硷的微量测定。溶媒系统包括甲酸乙酸,丙酸及醋酐。终点由目视法及电位法确定。在水中具有PK硷值为12或小于12的有机硷可在醋酸中进行滴定,目视及电位法均可用来确定终点。在水中,具有PK硷值大于13.5的弱硷可在醋酐中进行,滴定多需在0℃进行;亦可用目视或电位法决定终点。丙酸及甲酸亦有可
In this paper, the determination of organic base with 0.01N perchloric acid solution as a standard solution. Solvent systems include formic acid, propionic acid and acetic anhydride. End point by the visual method and potential method. Organic bases with a pH of 12 or less in water can be titrated in acetic acid and both visualization and potentiometry can be used to determine the endpoint. In water, a weak base with a PK value of more than 13.5 can be carried out in acetic anhydride. The titration is usually carried out at 0 ° C. The end point can also be determined visually or potentiometrically. Propionic acid and formic acid are also acceptable
