Abstract: Dielectric constant measurements have been carried out in the one and two-phase regions near the critical point for the polar + polar binary liquid mixture nitromethane + 3-pentanol. In the two-phase region, evidence for the 2tßsingularity in the coexistence-curve diameter has been detected, thus confirming the novel predictions of complete scaling theory for liquid-liquid criticality. In the one-phase region, an “unusual” positive sign for the amplitude of the 1ta- singularity has been encountered for the first time in a binary liquid mixture at atmospheric pressure. Mass density measurements have also been carried out to provide additional information related to such experimental finding, which entails an increase of the critical temperature Tc under an electric field.
