Vapor pressures of hydrocarbons: modelling, extrapolation and prediction

A general method is proposed for formulating equations with which vapour pressures can be reproduced in wide reduced temperature ranges. The problem of low and high pressure extrapolation is discussed. The method is applied to vapour pressures of hydrocarbons and illustrated by results obtained with...

Description
Summary:A general method is proposed for formulating equations with which vapour pressures can be reproduced in wide reduced temperature ranges. The problem of low and high pressure extrapolation is discussed. The method is applied to vapour pressures of hydrocarbons and illustrated by results obtained with 160 compounds.
