Synthesis and Characterization of Azido Esters as Green Energetic Plasticizers

Abstract Three azido‐esters based green energetic plasticizers were synthesized from their chlorides including DEGBAA (diethyleneglycol bis(azidoacetate)), DPGBAA (dipropyleneglycol bis(azidoacetate)) and HETTAA (hexanetriol tris(azidoacetate)). The syntheses carried out in a two‐step process: the first step was esterification of glycol or triol using chloroacetyl chloride, second substitution chloracetate with sodium azide that yields corresponding azido derivatives. parameters synthesis such as molar ratio hydroxyl acyl groups, amount type solvent (dimethyl sulfoxide dimethyl formamide) optimized to achieve maximal conversion purity products. obtained products characterized by elemental analysis, nuclear magnetic resonance (NMR), infrared vibrational spectroscopy (IR).
