Popis: Abstract In this work the chemistry of asymptotically AdS black hole, for the charged and uncharged solutions of Pure Lovelock gravity, is discussed. The charged case behaves as a Van der Waals fluid and whose first order phase transitions, between small stable/large stable black holes, are analogous to the liquid/gas phase transitions as in AdS black hole for Einstein Hilbert theory. However, the thermodynamics behavior differs from the generic Lovelock theory, because there is a unique critical point, unlike the generic case where there may be more than one critiackcal point. Also, it is shown that the thermodynamics behavior of the Pure Lovelock black holes (in the extended phase space) can be represented by variables that are analytic functions of n and d, where n corresponds to the highest power of the Riemann tensor in the Lagrangian and d corresponds to the number of dimensions. This allows to obtain several results. For instance, the critical compressibility factor Z is a function of n and d that satisfies $$Z
