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.Comments: Refs. 9, Tabs. 0, Figs. 4.
