Thymol, Surface Tension

Figure 14.29. Temperature-dependence of the liquid-vapour surface tension for thymol at and above is melting point (51.5°C)...

Figure 14.30. Temperature-dependence of the contact angle, 6, of glycerol on solid thymol, determined from the capillary rise, /i, on a flat vertical surface, and the temperature-dependence of the resulting surface tension, /sv, of thymol in the solid state (from ref. (52))...

As there is a need for more matrix materials than are presently available, thymol will be introduced for this purpose. This requires the determination of the viscosity of thymol and its liquid and solid surface tension, and Tgy respectively. 

In the second part, thymol will be used as a matrix material to determine the surface tension, Tpy> small... 

The viscosity of thymol and all other matrix materials presented in this paper were measured with an Ostwald viscometer placed in a liquid bath at the melting point of the matrix material. The surface tension, for thymol at its melting... 

Having measured the required physical properties for thymol, it is now possible to determine particle surface tensions, y-p t from critical velocity measurements using this matrix.
