Azido plasticizers

Azido Plasticizers A large number of compounds with azide functionality have been reported in the literature [194—199] and they appear to be potential energetic plasticizers. A brief summary of these azidoester plasticizers, that is, synthesis, 

We have also synthesized bis(2-azidoethyl) adipate (BAEA) by the reaction of bis(2-chloro ethyl) adipate (BCEA) and sodium azide in ethanol medium and characterized the product for solubility, density, refractive index, impact sensitivity, thermal behavior and moisture content [171]. These properties suggest that a part of non-energetic plasticizers, that is, , DEP, DOP etc. can be replaced by BAEA in propellant formulations thereby resulting in increase in their fsp.

Keywords Plasticizer, Energetic Plasticizers, Azido Plasticizers. 

Drees and co-workers synthesized a number of energetic azido plasticizers whose structures are based on those of known nitrate ester plasticizers. EGBAA (3), DEGBAA (4), TMNTA (5) and PETKAA (6) are synthesized from the corresponding chloroacetate esters with sodium azide in DMSO. 

Uses. n-Pentane has found use as an anesthetic an expl suppressant when mixed with a halogen-ated hydrocarbon and included in aircraft fuel (Ref 13) a jet engine fuel (Ref 16a) as a base for synthetic rubbers and plastics a parent compd for the formation of nitropentanes and azido nitro pentanes used as expls and propints (Refs 15a, 15b 21a) also, as a parent compd for fluorine-contg resin binders which impart both thermal stability and, in conjunction with metal hydrides, high impulse to solid propints (Ref 15b)...

Azido nitroamino compounds and azido compounds have been synthesized large quantitatively. They are used in energetic plasticizers and energetic oxidants [34] according their properties.
