The density and viscosity data of two biodiesel components methyl dodecanoate and ethyl dodecanoate over the temperature range from (302-354) K and at pressures up to 15.2 MPa were reported. Experimental results show that the densities and viscosities of methyl dodecanoate and ethyl dodecanoate increase with the increase of pressure and decrease with the increase of temperature. The densities and viscosities of different fatty acid methyl esters and fatty acid ethyl esters were compared to investigate the effect of carbon number. Tait equation and Andrade-Tait model were used to model the measured densities and viscosities of methyl dodecanoate and ethyl dodecanoate.
