Abstract
We report here pressure studies on eight pure compounds all of which exhibit the reentrant nematic phase at atmospheric pressure. In all cases the smectic A-nematic phase boundary has an elliptic shape. For two of the substances, the smectic A-reentrant nematic transition changes its character from monotropic to enantiotropic at high pressures. The maximum pressure of stability of the smectic A phase is seen to be related to the range of the nematic phase at atmospheric pressureKeywords
