ABSTRACT
The low-temperature heat capacities of trans-4-(aminomethyl)cyclohexanecarboxylic acid were measured with an adiabatic calorimeter over the temperature range from (82 to 378) K. The heat capacity curve was smooth and continuous, which indicated that the compound was stable over the whole temperature range. Thermal decompositions of the compound were studied by thermogravimetry (TG) and the possible mechanism of the thermal decomposition was deduced. The energy of combustion of the compound was determined, and the standard enthalpy of combustion, centscHpounds, and standard enthalpy of formation, centsfHpounds, were calculated.
