Abstract
Colorimetric or potentiometric titration of the aldehyde residues in polyaldehyde dextran by the hydroxylamine hydrochloride/sodium hydroxide method has been found to be a convenient and accurate method to determine formyl content. Nitrogen combustion analyses on the isolated oximes confirmed the titrametric results.
摘要
已发现通过盐酸羟胺/氢氧化钠法对聚醛葡聚糖中的醛基进行比色滴定或电位滴定是一种方便且准确的测定甲酰基含量的方法。对分离出的肟进行的氮燃烧分析证实了滴定结果。
