λr PΦNOMENCLATUREDDcDr= density in gm/cc= critical density in gm/cc= reduced density, D/DcDSLDSV= density of saturated liquid, gm/cc= density of saturated vapor, gm/ccH* = enthalpy of ideal gas in cal/g-moleHSLΔH*= enthalpy of saturated liquid, cal/g-mole= difference between ideal enthalpies at-19°C. and a higher temperature,cal/g-mole= heat of vaporization, cal/g-moleMP= molecular weight= pressure in atmospherec P= critical pressure, atm.= reduced pressure, P/P c= atomic and structural constant in Eq. (2)due to -CHO group.R= gas constant, 1.987 cal/g-mole/°K= 82.06(((cc)(atm.))/((g-mole)(°K)))S* = entropy of ideal gas, cal/g-mole/°KSSL = entropy of saturated liquid, cal/g-mole/°KSSV= entropy of saturated vapor, cal/g-mole/°Kiv
