An experimental heat-transfer system as well as a data reduction procedure was established in this study on the basis of the fundamental theory of liquid crystal thermography with heating at the solid surface. The system was tested by using both the steady-state and the transient methods with single-step heating at the surface. Two problems considered in the test were the flow over a flat plat with an unheated starting length and a uniformly heated cylinder in the cross flow.

The phase equilibrium data of SBO-FAME-Methanol, SBO-FAEE-Ethanol and Glycerol-FAEE-Ethanol systems were measured. The results indicated that it involved two different stages: liquid-liquid-solid reaction stage and liquid-solid reaction stage. When the molar ratio of methanol to oil is 12:1 at 65℃, the turning point is at a 55% biodiesel yield. The liquid-liquid-solid reaction model was proposed based on the double-membranes theory. It indicated that the process is reaction and mass transfer controlled together at the first stage, and the second stage is reaction controlled. The predictions of the model are matched with the experimental results.In the end, the acid was extracted using methanol and ethanol from jatropha curcas l oil.
