The effect of proton ordering in thermal conductivity of clathrate tetrahydrofuran hydrate
The effect of proton ordering in tetrahydrofuran hydrate has been detected using a technique based on
 measurement of thermal conductivity. The thermal conductivity of tetrahydrofuran hydrate was measured
 by the steady-state potentiometric method in an interval of 2–150 K. Two regim...

| description | The effect of proton ordering in tetrahydrofuran hydrate has been detected using a technique based on
measurement of thermal conductivity. The thermal conductivity of tetrahydrofuran hydrate was measured
by the steady-state potentiometric method in an interval of 2–150 K. Two regimes were selected to observe
the effect: (i) slow cooling of the hydrate sample and (ii) doping the hydrate with a small quantity of KOH alkali
to a concentration of 10⁻⁴. Proton ordering affects the temperature dependence of the thermal conductivity
changing its glass-like behavior to crystal-like below 150 K. The phonon maximum that appears in the
temperature dependence of the thermal conductivity at T = 17 K is attributed to the cooperative process of
local proton ordering stimulated by orientational and ionic defects.
