Di-s-butylbenzene-2-sulfonyl chloride, like the corresponding diisopropylbenzene derivative,* loses an alkyl group on nitration. There is evidence pointing to partial loss of a s- butyl. group when 1, 4-di-s-butylbenzene reacts with chlorosulfonic acid, since after hydrolysis of the resulting sulfonyl chloride, the second crop of sulfonic acid sodium salt contains a rather high per cent. of sodium.
