The possibility of obtainingN, N'-dialkyl methylenebisnitramines from primarynitramines and formaldehyde in dilute H2SO4 (65–85%) has been shown. The reaction starting from two different nitramines results in a mixture of one asymmetrically and two symmetrically substituted products.

Crystal structures of seven methylenedinitramines with plasticising ability have been determined. These molecules, appropriate as energetic plasticisers of propellants, are used to give an environmental temperature independent combustion. The dinitramines are synthesized by condensation reactions of nitramines with formaldehyde in an acidic medium. This work gives their melting point and their melting enthalpy. Glass transition temperatures are also measured. (C) 2002 Elsevier Science B.V. All rights reserved.
