How to stabilize polysubstituted 0-phenylene diamine from atmospheric oxidation?

12 December 2017 1 7K Report

Finding difficulty in stabilizing polysubstituted 0-phenylene diamine, as it is getting converted to N-oxides in atmosphere.

How to overcome this problem?

Is there any chemical way to stabilize it?

Anton Tyurin

You can improve stability by using the salt of diamine or its acidified solutions. And, of course, storaging under argon or nitrogen, in solid state is preferrably for all air-sensetive compounds.
