Studies On Synthesis Of Aza-bridged Calix[6]arene And Complex With RDX And HMX

It's a popular problem to debase explosive sensitivity.This paper presents therecommendations of debasing explosive sensitivity by supramolecular complex.On the baseof synthesizing aza-bridged calix[6]arene,carry through the research of supramolecularcomplex with RDX and HMX.Cyanuric chloride,p-phenylenediamine and m-phenylenediamine were used as mainmaterials in the experiment, potassium carbonate or potassium hydroxide were taken asneutralisatal reagents. First of all, synthesize aza-bridged calix[6]arene middle substances M1,namely N,N′-di(4,6-dichlorine-1,3,5-s-triazine-2-base)- 1,4- dipheylamine,M3, namelyN,N′-di(4,6-dichlorine-1,3,5-s-triazine-2-base)-1,3-diphey-lamine,M2, namely2,4-di(4-amidocyanogenbenzene amidocyanogen)-6-chlorine-1,3,5-s-triazine M4, namely2,4- di(4-amidocyanogenm-benzeneamidocyanogen)-6-chlorine-1,3,5-s-triazine,then ultimate productions azabridged-[3] p- phenylenediamine-[3] s-triazine calix[6]arene C1 and aza-bridged-[3] m-phenylenediamine-[3] s-triazine calix[6]arene C2 were synthesized through taking M1(or M3) andM2(or M4) as materials. On the base of synthesizing aza-bridged calix[6]arene,azidesderivative C3 and nitro derivatives C4 were got . Synthetic substances were characterizedthrough IR and 1H NMR.It carried through the structural optimization of host C1 and C3,guest and supramoleculesystem by quantum chemistry half -empirical AM1 and DFT-B3LYP methods.The results ofUV-visible spectrum in DMF indicated that C1 and C3 maked RDX change. The quantityrelative ratio was1:1. The supramolecular complex with RDX and HMX were characterizedthrough XRD.The XRD results indicated that the supramolecular complex with RDX andHMX were different from host,guest and their mixture.
