| Abstract: | The 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. |
