Structure-property quantitative correlations for the density of primary normal alcohols

The procedure is proposed for calculating and predicting the density of liquid primary normal alcohols at temperatures from 293 to 498 K and pressures from 0.1 to 50 MPa, based on correlation for the classes of substances that form homologous series, in which the physicochemical properties change monotonically. The coefficients of a generalized function are calculated, depending on the temperature, pressure, and the number of carbon atoms in an alcohol molecule. The calculation results are compared with the initial data. The discrepancy for the most reliable data is less than 0.3%.
