摘要
本文对浓中性盐存在时,用盐酸标准溶液直接滴定吡啶进行了研究。于饱和氯化钠介质中用指示剂法和电位滴定法测定吡啶的含量,并与国家标准GB—689—65法所得结果进行对照,结果较为满意。
The direct titration of pyridine with aqueous standard solution of hydrochloric acid in the presence of concentrated neutral salts have been studied. The content of pyridine was determined quantitatively by potentiometric method and use of indicators in the medium of saturated sodium chlorde. The method is compared with the National Standard Method-GB-689-65 and the result is satisfactory.
