## Abstract A method is described for the determination of traces of basic nitrogen in hydrocarbons and the like by titration with perchloric acid in glacial acetic acid in the complete absence of water. Enough glacial acetic acid is added to the sample to keep perchlorates of bases in solution, an
In a previous papcrl it was shown that, under suitable conditions, a yellow dioxanc solution of z,z',4,4',G,G'-hexanitrodiphenylaminc (= HNDA) was turned orange or red on the addition of pyridine through the dissociation of the acid, giving red anions.
