Results
The measured and calculated values of Vinylcyclohexane are given in the following table 1.
The static method is suitable to determine the vapour pressure (in the range of 10 to 10^5 Pa). The values obtained from decreasing the temperature coincides with the curve obtained for increasing temperature. The resulting vapour pressure curve can be utilised for calculation of the vapour pressure of the sample. The vapour pressure of Vinylcyclohexane is assigned to be 1.94 x 10^3 Pa at 20 °C and 2.47 x 10^3 Pa at 25 °C.
