Meixner's historical remark in 1969 "... it can be shown that the concept of entropy in the absence of equilibrium is in fact not only questionable but that it cannot even be defined...." is investigated from today's insight. Several statements --such as the three laws of phenomenological thermodynamics, the embedding theorem and the adiabatical uniqueness-- are used to get rid of non-equilibrium entropy as a primitive concept. In this framework, Clausius inequality of open systems can be derived by use of the defining inequalities which establish the non-equilibrium quantities contact temperature and non-equilibrium molar entropy which allow to describe the interaction between the Schottky system and its controlling equilibrium environment.

Isobaric heat capacities of C[Formula: see text](OH)[Formula: see text] and C[Formula: see text](OH)[Formula: see text] fullerenols were measured using adiabatic calorimetry in the temperature range of 0–320[Formula: see text]K along with standard thermodynamic functions: [Formula: see text], [[Formula: see text]] and [[Formula: see text]]. Furthermore, the molar entropy of formation and the molar third law entropy of C[Formula: see text](OH)[Formula: see text] and C[Formula: see text](OH)[Formula: see text] in crystalline state at 298.15[Formula: see text]K were calculated.
