Methods for the Syntheses of Mono-, Di-, Tri- and Tetranitro Derivatives of Diphenylamine.
Abstract
Diphenylamine, 2-nitrodiphenylamine and Akardite (1,1-diphenylurea) are commonly used stabilisers for propellants. Their action is to remove oxides of nitrogen formed in propellant decomposition by which they are converted to a range of diarylnitrosamines and nitrodiphenylamines. Nitration of the aromatic nuclei proceeds to an increasing extent with aging of propellant ultimately giving 2,2',4,4',6,6'-hexanitrodiphenylamine on extended storage at elevated temperatures. The methods that have been used to prepare those mono-, di-, tri-and tetranitrodiphenylamines which are potentially to be found in propellants are discussed and evaluated. Experimental details are given by which samples of each of these compounds have been prepared.
