摘要：
This work aims to present results of density (rho(L)), isobaric thermal expansivity coefficient (alpha(P,L)) and isothermal compressibility coefficient (k(T,L)) correlations for n-dodecane and n-nonane as a function of temperature and pressure, able to obtain these properties at any temperature and pressure in the range of 4 degrees C to 40 degrees C and 0.1 MPa to 15.0 MPa, with low uncertainties (in the case of n-dodecane: 0.00025 g.cm(-3) for rho(L); 0.00020 degrees C-1 for alpha(P,L) and 0.00022 MPa-1 for k(T,L) and in the case of n-nonane: 0.00026 g.cm(-3) for rho(L), 0.00006 degrees C-1 for alpha(P,L) and 0.00032 MPa-1 for k(T,L)). The density measurements were performed using a pycnometer that was calibrated which presents a volume uncertainty of 0.020 cm(3).
