Abstract:A generalized scaled equation of state has been developed to calculate thermodynamic properties of n-alkanes from methane (CH4) to n-nonane (C9H20) in the critical region. The equation is valid in the reduced density range 0.7lesrgr cles1.3 at T=T c and up to 1.2T c at rgr=rgr c.
Keywords:critical parameters  critical phenomena  equation of state  methane  ethane  n-alkanes  specific heat  sound velocity
