| Abstract: | Molar heat capacities of 4‐(aminomethyl)benzoic acid were precisely measured with a small sample precision automated adiabatic calorimeter over the temperature range from 80 to 400 K, and the heat capacity data were fitted to a polynomial equation: Cp,m=162.01+91.771X+6.4372X2+1.7517X3?4.991X4+8.909X5+1.585X6, X= (T?235)/155. The constant‐volume energy of combustion of the compound was measured by means of a precision oxygen bomb combustion calorimeter. The standard enthalpy values of combustion and formation were determined to be: ΔcHm?= ? (4300±4) kJ·mol?1 and ΔfHm?= ?(420±5) kJ·mol?1. |
