反応手順
In another proposed method for synthesis of the aforementioned mixture of three dinitro-diaza-alkanes, methylamine or ethylamine is reacted with a chloroformic acid ester using sodium hydroxide solution to form an intermediate product which is then nitrated with nitric acid. The nitration product is reacted by means of ammonia and ethanol at reflux to form methylnitroamine or ethylnitroamine, which is then condensed to form the dinitro-diaza-alkanes as in the preceding method. In this process, the next-to-last step in the synthesis of the nitroamines is very complicated and time-intensive, so that it cannot be implemented on a large scale industrially.
