In this article the results of the ex- perimental determination of a group of physical and transport properties of palm oil and of its methyl esters are presented, so as to generate reliable in- formation for the execution of works done by chemi- cal engineers, such as the modeling, the equipment sizing and the simulation of processes. Melting ranges, heats of fusion, boiling points, heats of com- bustion, were experimentally determined, and den- sity, viscosity and heat capacity as a function of tem- perature were measured. The experimental values were adjusted to empirical models. In addition, den- sity, viscosity and heat capacity as a function of tem- perature for three mixtures of palm oil and its methyl esters were measured, from where it was concluded that the density and heat capacity can be calculated as if the mixture would behave as ideal solutions, while the viscosity can be calculated with Andrade's model. government has identified this potential, and based on the legislation promotes the cultivation of African palm (Elaeis guineensis) and the production of biodiesel, which by the year 2008 will be added to the petro- chemical diesel in order to replace the 5%, in a similar way to that used for the oxygenation of gasoline with ethanol. In this study the results of the measurement of some physical and transport properties of palm oil, its methyl esters and three of its mixtures, are presented. Melting ranges, heats of fusion, boiling points and heats of combustion were experimentally determined, and the properties density, heat capacity and viscosity, were
