Synthesis and Characterization of Energetic Plasticizer 2,3-Bis(hydroxymethyl)-2,3-dinitro-1,4-butanediol Tetrabenzoate

Synthesis of 2,3-bis(hydroxymethyl)-2,3-dinitro-1,4-butanediol tetrabenzoate (BHDBTB) with activa-tor of 4-dimethylaminopyridine (DMAP) and dehydrant of N,N-dicyclohexylcarbodiimide(DCC) has been carried out by esterification of 2,3-bis(hydroxymethyl)-2,3 dinitro-1,4-butanediol(BHDB) and benzoic acid. Structure of product was characterized by 1H NMR, 13C NMR and IR. The results of X-ray single-crystal diffraction show that BHDBTB belongs to triclinic system;the space group is P-1, Mr= 656.58. The crystal cell data of product were: a=8.851 nm,b=9.373 nm,c=10.211 nm,α=82.61°,β=83.31°,γ=67.74°,V=775.3 nm3,Z=2,Dc=1.406 g/cm3,R1=0.083 6,Rw2=0.086 1.
