Methylazide-substituted 1,3-dioxolanes of the generic formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are independently selected from H, C.sub.1 -C.sub.6 alkyl and CH.sub.2 N.sub.3 are disclosed as energetic plasticizers for rocket and gun propellants and explosives formulations. Methods of preparation of these compounds are also disclosed, in which halogen-substituted vicinal diols are reacted with aldehydes or ketones to form the halo-analog of the product, which is then converted to the product by reaction with a metal azide.

Energetic azidomethyl-substituted 1,3-dioxolanes

Novel multi-azido formals, acetals and ketals are disclosed, having the following generic formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7 and R.sup.8 are independently selected from H, CH.sub.3, and CH.sub.2 N.sub.3, and methods of preparation of these compounds.

Energetic azide plasticizer

This patent discloses and claims the reaction of oxirane-containing compounds with primary cyclic imide-containing compounds, at temperatures of from about 0.degree. to 225.degree.C, in the presence of active chromium III tricarboxylate salts which have unoccupied coordination sites.
