Abstract
The thermal pressure coefficients of ethanol and cyclohexane liquid mi xtures over the range of temperature from 25 degrees C to 65 degrees C were mesaured. The modified van der Waals' model suggested by our pre vious work is also applicable to these mixtures satisfactorily. From t he parameter of model, B/A(2),a quantitative relationship between the destruction of self-association of ethanol and the concentration is ob tained. It is found that the internal pressures of the mixtures depend not only on those of two pure components,but on the interaction param eter A(12).
