I need information on gasoline vapour pressure at different temperature, in particular in the 20°C to 80°C range. Keep people away. Budavari, S. Cyclohexane is known to undergo oxidative metabolism to yield cyclohexanol (major metabolite), cyclohexanone, and possibly other oxidative products (1,2- or 1,4-dihydroxycyclohexane and its corresponding ketone analogs).

The experimental data shown in these pages are freely available and have been published already in the DDB Explorer Edition. Thermodynamic Properties of n-Hexane (Temperature Basis) - Saturation Region: Temperature: Saturation pressure, bar: Density of liquid, kg/m 3: Specific volume of vapour, m 3 /kg: Enthalpy, kJ/kg

Plots of the vapor pressures of benzene (\(C_6H_6\)) and toluene (\(C_6H_5CH_3\)) versus the mole fractions at 20°C are straight lines. now, total pressure of solution, = 0.2 × 400 + 0.8 × 120 = 80 + 96 = 176 mm Hg.
