摘　　要：研究了过碱性重烷基苯磺酸钙清净剂的烃基结构 ,通过使用 EIMS(电子轰击质谱 )、ESI MS(电喷雾质谱 )、红外光谱等现代实验技术 ,直接测定经转化处理过的磺酸钙清净剂 ,得出其主要的烷基芳烃化学组成为单烷基苯和对位二烷基苯 ,含量占 42 % ;茚满、苯骈二环己烷类化合物、烷基萘和苊类化合物 ,含量约 47.7%。烷基芳烃部分的平均相对分子质量是 3 2The alkyl group structure of overbased calcium alkyl benzene sulfonate has been studied by EIMS, ESIMS and IR spectra. The results showed that the main alkyl aromatics were consisted of monoalkyl benzene and para dialkyl benzene, their total content was ca. 42%. Other compounds such as indane, benzocyclohexane, alkylnaphthalene and acenaphthene dirivatives were also existed and their total content was ca. 47.7%. The average molecular weight of alkyl aromatic components was 322.
