| Abstract: | The following acetylated derivatives of indazole: 3-indazolone, l-acetyl-3-indazolone, 2-acetyl-3-indazolone, l,2-diacetyl-3-indazolone and 3-acetoxy-l-acetyl-indazole were studied by combustion calorimetry. The enthalpies of formation were calculated from enthalpies of combustion. The isomeri-sation enthalpies were also calculated. The phase transition temperatures as well as caloric capacities of the studied compound in the crystalline phase were determined by DSC. |
