Abstract

The i-factors in 100% sulfuric acid have been measured by the freezing point method for the series RICOH where R equals p-tolyl, p-nitrophenyl, p-chlorophenyl, p-aminophenyl, p- dimethylaminophenyl, and in addition di-(p-dimethylaminophenyl)-phenylcarbinol. The spectra of the above carbinols in 100% acid has been examined in the region 200-600 mp Both types of experiments indicate that all three rings are probably not involved in the ...
