  It is shown that the equations for pressure, entropy and the isochoric heat
capacity obtained by using generalization of the equilibrium thermodynamics in
fractional derivatives in the paper mentioned above are approximate, the
comparison of the equations with the experimental (tabulated) data for Neon and
Argon made in the paper is incorrect, and the conclusions of the paper made on
the basis of the comparison could be incorrect. The conditions for validity of
the equations are established. It is also established that the question about a
physical sense of the exponent of the derivative of a fractional order is still
open.
