A gas chromatography and gas chromatography mass spectrometry study was performed on four commercial linear alkylbenzenes (LAB). A preliminary detailed analysis was done on some model compounds: four tetralin mixtures obtained by alkylation of benzene with linear dichloro n-paraffins (C, C, C, and C), 1-methyl-4-heptyltetralin and 1-methyl-3-octylindane. We concentrated on the minor components (5-10%) present in the linear alkylbenzenes. Three different types of compounds were identified: A) branched alkylbenzenes, B) 1,4-dialkyltetralins with linear alkyl groups, and C) 1,4-dialkyltetralins with branched alkyl groups. Quantitative evaluation of these minor components was also done. No evidence of 1,3-dialkylindane structures, at least those with linear alkyl groups, was found in the commercial linear alkylbenzenes studied. [ABSTRACT FROM AUTHOR] |
