Flow properties of alicyclic compounds as traction fluids

Several alicyclic compounds, model compounds of traction fluids, were synthesized and the high-pressure viscosity was measured with a rolling viscometer. The relation between the molecular structure of the synthetic alicyclic compounds and their activation quantities for viscous flow is discussed. A useful structure-property guideline for the design of better traction fluids is presented. The relation between these flow activation quantities is also discussed. It was found that his relation could be used to estimate the pressure dependence of the viscosity from the temperature dependence of the viscosity.
