标准摘要
[中文适用范围]: 样品被新生氢碘酸水解。 用标准容量硫代硫酸钠溶液滴定释放的碘。 该方法适用于饱和伯脂肪醇、油醇、饱和脂肪酸、直链和支链烷基酚的聚乙氧基化衍生物的分析。 不适用于含硫或氮的化合物、含氧丙烯基的化合物、醛或缩醛、甾醇及其衍生物。 [外文原描述]: The sample is hydrolyzed by nascent hydroiodic acid. The iodine liberated is titrated with a standard volumetric sodium thiosulfate solution. The method is applicable to the analysis of polyethoxylated derivatives of primary saturated fatty alcohols, oleyl alcohol, satureted fatty acids, straight and branched chain alkylphenols. It is not applicable in the present of compounds containing sulfur or nitrogen, compounds containing oxypropylene group, aldehydes or acetals, sterols and derivatives.
英文名称Non-ionic surface active agents — Polyethoxylated derivatives — Iodometric determination of oxyethylene groups
