Abstract

Abstract TO FORM A GROUP OF THE FORMULA ARE PREPARED BY REACTING AN AMINE OF THE FORMULA WHERE R represents H, and alkyl group of 1 to 6 carbon atoms or an alkyl group of 1 to 6 carbon atoms where at least one hydrogen atom has been replaced by the group Compounds of the formula D R A W I N G WHERE R'' represents H, -NH-NO2, alkyl of 1 to 6 carbon atoms or alkyl of 1 to 6 carbon atoms where at least one hydrogen atom has been replaced by -NH-NO2 to form the group -CH2NH-NO2 with formaldehyde and HCl to effect a chloromethylation and thereafter reacting an ionic azide with the chloromethylated product. The compounds are used in double-base propellents as a partial or total substitute for the nitroglycerin portion of the propellant.
