Notes: Abstract Two compounds of sulphamide type:p-amino-benzene sulphonamide (I) and 3,4-dimethylisoxazol 5-sulphanylamide (II) were studied by combustion calorimetry and by differential scanning calorimetry (DSC). The enthalpies in solid state at 298,15 K of combustion, δc H m o (I)=-2788,5±1,6 kJ mol−1, δc H m o (II)=-5036±3,8 kJ mol−1 and of formation, δf H m o (I)=-458,3±1,6 kJ mol−1, δfH m o (II)=-180,1±3,8 kJ mol−1 were determined. The thermal effects concerning the melting and phase transition of this compounds were also measured.
