Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. Octane (C.H,) has a vapor pressure of 14.3 torr and a density of 0.703 g/mL. Octane has a vapor pressure of 40. One of these isomers, 2,2,4-trimethylpentane (commonly called iso-octane) is used as one of the standard values in the octane rating scale. SANGI, , , 2 , , 13,8 . How to find the mole of fracture? A vapor-suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. *. n-Octane (C 8 H 18) is a colorless liquid that is insoluble in water. Torr at 45.1c and 400. The vapor pressure of liquid octane, C8H18, is 100 mm Hg at 339 K. A sample of C8H18 is placed in a closed, evacuated 537 mL container at a temperature of 339 K. It is found that all of the C8H18 is in the vapor phase and that the pressure is 68.0 mm Hg. n-Octane, normal-Octane Colorless liquid with a gasoline-like odor. Octane = 400 mm Hg .
