AZIDO DERIVATIVES OF PENTAERYTHRITOL

Abstract

Diazido derivatives of pentaerythritol are prepared by reacting 3,3-bis(azidomethyl) oxetane with inorganic acids such as hydrobromic or nitric acid. The resulting diazido monobromide can be reacted with sodium azide to produce pentaerythritol triazide which can be subsequently nitrated to pentaerythritol triazido mononitrate. The pentaerythritol diazido mononitrate produced by the reaction of nitric acid with the above oxetane can be further nitrated with nitric acid to produce pentaerythritol diazido dinitrate. These diazido and triazido derivatives of pentaerythritol can be utilized as energetic azido plasticizers per se or can serve as intermediates for the production of such plasticizers.
