抄録

Sulfonation behaviors of commercial alkylbenzenes were determined by using gas chromatography according to the previous report. <BR>The relative sulfonation rates of all isomers, contained in soft type alkylbenzene (Nalkene ML-N 500), were obtained. These rates showed that in the sulfonation with 20% oleum there exist great selectivity owing to the benzene ring position and the alkyl chain length. But the change of the average molecular weight of the unsulfonated alkylbenzene was rather small. In the case of sulfur trioxide sulfonation, the selectivity is smaller than that of oleum. And it was suggested that this method, involved in the determination of change of the chromatogram by sulfonation, is also useful to estimate the components of impurities contained in commercial alkylbenzenes. <BR>Hard type alkylbenzene was not clearly separated by the gas chromatography using packed column, and the change of composition by sulfonation was not observed clearly, thus the selectivity was not clear.
