标准范围

在单独的试验部分进行以下测定:测量甲醇介质中的表观pH值；水含量的测定；伯胺、仲胺和叔胺含量分布的测定；氧乙烯基含量的测定；硫酸灰分的测定。此外，制备供试品的水溶液或甲醇溶液，并分离游离聚乙二醇。在分离的聚乙二醇上，确认不含氮，并测定其相对分子质量。

On separate test portions the following determinations are carried out: measurement of the apparent pH in methanolic medium; determination of the water content; determination of the distribution of primary, secondary and tertiary amines contents; determination of oxyethylene groups content; determination of sulphated ash. Furthermore an aqueous or methanolic solution of a test portion is prepared and the free polyethylene glycols are isolated. On the separated polyethylene glycols the absence of nitrogen is verified and their relative molecular mass is determined.
