摘要：采用质谱场解吸电离、~1H核磁共振以及反门控去偶的^(13)C核磁共振等分析方法和一些特殊实验技术,直接测定润滑油清净分散剂——石油磺酸盐的分子量分布,平均分子量、烷基芳烃部分的结构等。分析结果与前人采用脱磺酸根后分析的结果基本一致,而分析的前处理工作大大简化。表明本工作采用的分析方法是合理的,所得结果是可行的。
Field desorption of mass spectrometry, ~1H NMR, and inverse gated decouping of ^(13)C NMR are used to analyze calcium petroleum sulphonates used as detergen-dispersant additive for lubricating oil directly. The analytical results, involving distribution of molecular weight, average molecular weight, structure of the hydrocarbon portion of the sulphonates and so on, are the same as those obtained from a reported method, in which the samples were an alyzed only after hydrolysed to the corresponding hydrocabons. The pre-treament of our method is much easier than before.
