摘要
采用原样脱除稀释油后直接分析和酸化处理后分析的两种方法，分别对大连石化公司提供的１＃和２＃合成烷基芳基磺酸钙样品进行了元素、平均分子质量测定。确定了１＃和２＃样平均分子式和平均分子结构。结果表明，两种方法所得结果完全一致。所以，直接法可替代较复杂的酸化法。并且研究结果表明ＩＲ、１Ｈ－ＮＭＲ等分析方法直接用于分析合成烷基芳基磺酸钙混合物类复杂的化合物是切实可行的，所得结果可靠。
The element compositions and the average molecular weights of two synthesized alkyl aryl calcium sulphates, which were provided by Dalian petrochemical company, were determined by using two methods. The average formula and the average molecular structure of the two samples were infered. The same results were obtained by using the two methods so that the direct method can be used in stead of complex acidizing method. The study also shows that the means of IR, 1 H-NMR etc. can be directly applied in the analysis on alkyl aryl sulfonates-like complex componds, which is reasonable and feasibe. The results are reliable.
