A linear-by-mole blending rule for octane numbers of n-heptane/iso-octane/toluene mixtures

Research and Motor Octane Number (RON and MON, respectively) measurements were performed to assess a linear-by-mole computation method for octane number prediction based on pure compound values. Measurements demonstrated that a linear computation method is accurate for ternary mixtures of n-heptane, iso-octane and toluene, with a very high level of accuracy for RON, MON and sensitivity in the range of values of actual gasolines. The relation was...
