J. Reuter et al., DIFFERENTIAL THERMAL-ANALYSIS UNDER PRESSURE ON CYANOCYCLOHEXANE, ,4-TETRAHYDRO-5,6-DIMETHYL-1,4-METHANONAPHTHALENE, AND 2-METHYL-2-PROPANOL, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 48(5-6), 1993, pp. 705-708
Differential thermal analysis has been performed on cyanocyclohexane (
CCH), 3,4-tetrahydro-5,6-dimethyl-1,4-methanonaphthalene (TDMN), and 2
-methyl-2-propanol (t-butanol) up to 300 MPa. The latter compound was
also investigated dielectrically. CCH displays an ODIC phase that tran
sforms only reluctantly to the low-temperature stable phase II. Anneal
ing under pressure can appreciably accelerate this transformation. For
all three compounds the phase diagrams were established. For CCH and
TDMN also the pressure dependence of the glass transition has been det
ermined.
