Thermochemical Study of Some e-beam Irradiated Guanidine Derivatives Compounds

Abstract:

The aim of this study was the investigation of the electron beam (e-beam) irradiated compounds derived from guanidines, implicated in the urea cycle using thermodynamic methods. The irradiation was performed in the range (0- 100) kGy using accelerated electron beam in order to establish if irradiation can alter significantly the characteristics of the compounds. The studied compounds present biochemical importance (creatine monohydrated and anhydrous, creatinine and arginine) and their transformations: dehydration, fusion and decomposition processes arising from heating were revealed from the recorded thermal profiles in the temperature range (25- 500) °C, using a coupled thermogravimetry (TG) and differential scanning calorimetry (DSC). The thermodynamic parameters (dehydration/ fusion/ decomposition temperatures, enthalpies, mass loss and purity) of the investigated compounds were slightly affected after e-beam irradiation with absorbed dose between (0- 100) kGy. In order to identify the characteristic groups, the corresponding chains and their conversion after irradiation, the Fourier transformed infrared (FTIR) method was used. The Mass Spectrometer (MS-MS) technique was employed to evidence the yields of the molecular products of the irradiation.
