- The thermal conductivity, λ, the heat capacity per unit volume, ρcp, and the phase diagram of 1,1,2-trichloroethane have been investigated in the temperature range 115 to 300 K and at pressures up to 2.5 GPa. The transient hot-wite method was used for the simultaneous measurement of λ and ρcp. Only solid phases I and II were detected, in agreement with the known phase diagram. A phase I-II transition was detected at about 200K and 0.1 GPa, which are conditions under which it had not priviously been observed. It was doubtful whether phase I could be retained metastably to low temperatures at low pressures with the most rapid cooling rate we were able to employ. The thermal resistivity of phase I was proportioned to temperature. The thermal resistivity of phase II contained an additional constant term, which we inferred to be a residual contribution associated with static structural imperfection in this phase.
