WebFor n-alkanes and branched alkanes, the MIR-boiling point relationships are described by a nonlinear regression equation to reflect their similarity in reactivity [MIR = 1.99 - 0.0034(BP) + 1.01 x 10-6 (BP) 2]. Using these equations, reactivity calculations for HCS can be modeled by a hypothetical n-alkane-branched-alkane species and a cycloalkane.
