ALIPHATIC NITRAMINES AND NITRAMIDES Nitramine nitramide

This is one of the simplest nitramines obtained by Thiele and Lachman [1] by the decomposition of nitrourethane  

The structure of the compound was the subject of controversy for some time [2]. However, the latest experiments of Clusius [3] with 15N-labelled nitramine have confirmed Thiele s formula [4]  

A carefully-devised method for preparing it was announced by Marlies, La Mer and Greenspan [5]. According to Bell and Wilson [6] the product contains some acidic impurities (about 1 %), possibly unchanged nitrourethane. 

This substance is an intermediate product of the decomposition of the important explosive nitroguanidine. It is also present in an aqueous solution of nitrourea or a sulphuric acid solution of nitrourea (Davis and Blanchard [7]). 

Nitramine is believed to occur in an ammonium nitrate solution in an excess of concentrated sulphuric acid as a result of the dehydration of this salt
