Thermochemical properties of three piperidine derivatives

1-benzyl-4-piperidinol, 4-benzylpiperidine and 4-piperidine-piperidine

Journal of Thermal Analysis and Calorimetry
Authors: M. Ribeiro da Silva and Joana Cabral


The standard (p o=0.1 MPa) molar energies of combustion for the crystalline 1-benzyl-4-piperidinol and 4-piperidine-piperidine, and for the liquid 4-benzylpiperidine, were measured by static bomb calorimetry, in oxygen, at T=298.15 K. The standard molar enthalpies of sublimation or vaporization, at T=298.15 K, of these three compounds were determined by Calvet microcalorimetry. Those values were used to derive the standard molar enthalpies of formation, at T=298.15 K, in their condensed and gaseous phase, respectively.
