Abstract
An equation for estimating the normal boiling points of homologous series with the general formula R1(CH2)nR2 has been developed. The equation is based on the hypothesis of functional self-similarity. The parameters of the equation have been determined using a current experimental database for 10 homologous series. The equation allows predicting the normal boiling temperature of any member of any homologous series of the type R1(CH2)nR2 if the normal boiling temperature is known for one compound which belongs to this series. The proposed method gives an absolute average percentage deviation from the experimental values of the normal boiling point of 0.72 % for all the homologous series studied. A thermodynamically consistent model for estimating the critical temperature, critical pressure, and normal boiling point of n-alkanes has been developed.
