Previously the process of equilibrium establishment in inhomogeneous
individual substances and binary mixtures near the liquids critical point
was studied. The temperature dependence of equilibrium establishment time in
such systems was founded to be nonmonotonical in presence of gravitational
field. In the context of fluctuation theory of phase transitions the
connection between this time and the velocity of centre mass movement for
inhomogeneous substance was revealed. In this report centre mass movement of
binary mixture methanol-hexane near the exfoliation critical point in
gravitational field was experimentally studied. The component movement
velocity dependences on temperature was researched and some particularities
of such process was analyzed. Viscosity of mixture was estimated and
analyzed as well.
