The chemical thermodynamic properties of alkanol(ROH) isomer groups from CH4O to C4H1 0O in the ideal gas phase have been calculated from 298.15 to 1000 K from tables of Stull, Westrum, and Sinke. In the absence of literature data on all isomers of higher isomer groups, the properties of isomers of C5H1 2O to C8H1 8O have been estimated using Benson group values. Equilibrium mole fractions within isomer groups have been calculated for the ideal gas state from 298.15 to 1000 K. For isomer group properties increments per carbon atom have been calculated to show the extent to which thermodynamic properties of higher isomer groups may be obtained by linear extrapolation. Values of C ○ P , S ○, Δf H ○, and Δf G ○ are given for all species of alkanols from CH4O to C8H1 8O in SI units for a standard state pressure of 1 bar.
