An exhaustive analysis of the critical behavior of the nematic to isotropic (N-to-I) phase transition on the
liquid crystal hexyloxycyanobiphenyl (6OCB) has been performed. To do so, the accurate evolution of various
physical magnitudes (static dielectric permittivity data together with specific heat and volumetric determinations)
around the N-to-I transition has been required. The specific heat data with the isobaric thermal expansion
coefficient and the derivative of the static dielectric permittivity with temperature have been proven to be
related to each other by a scaling relationship. However, some discrepancies have been observed for the
dielectric data in relation to such a scaling relationship and the critical behavior of the N-to-I phase transition.
All information has been used to get some insight on the strength of the first-order N-to-I phase transition of
the 6OCB in relation to the other counterparts in the nOCB series of compounds.
