| Abstract: | The boiling point (b. p.) change rule of fatty alcohols can be modelled and quantified by following QSPR equation In(800.386 - Tb) = 6.64919 - 2.94828 x 10-2NE 0.150955APEI, Where the NE is the effective length of carbon chain of alkyl group in the alcohol molecule. The APEI is the polarizability effect index difference between the corresponding branched and normal alkyl isomers containing the same carbon atom number, which expressed the effect of hydroxyl group on the boiling point of alcohols. |
