SELECTIVE DERIVATIZATION IN AQUEOUS SOLUTION OF AROMATIC AMINE AND ANALYTIC METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a method capable of selectively derivatizing aromatic amine even in the coexistence of non-aromatic amine and phenol and detecting and analyzing the same.;SOLUTION: Provided is a method for derivatizing aromatic amine characterized in that aromatic amine is treated with a halide in an aqueous solution of pH 4 to 5.5, and also provided is a method for detecting or quantifying aromatic amine in an aqueous solution characterized in that the N- acylated derivative of aromatic amine generated by the above method is detected or quantified.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2018,JPO&INPIT
