It has been found that both 2,6- and 2,7-di-t-butylnaphthalene form the same disulphonic acid when treated with 2 molar equivalents of chlorosulphonic acid. It is suggested that this acid is 2,6-di-t-butylnaphthalene-4,8-disulphonic acid. The evidence, including the n.m.r. spectrum, on which the proposed structure is based is presented.
