Comparative Analysis of Physical and Chemical Properties of Jatropha Oil

Abstract

Jatropha is a member of the Euphorbiaceae family. Its oil is used to produce biodiesel. The physical and chemical properties of the oil are important to determine the quality of the oil. For this purpose, we determined the density of oil with a pycnometer. Kinematic viscosity is measured by Ubbelohde capillary viscometer. The other properties discussed in this paper are iodine value, oxidation value, acidity, and flash point. Comparative analysis of the properties with existing fuel practices shows its suitability for diesel engines.
