Abstract: The objective of this work was to study the long term storage stability of JCB (Jatropha curcas biodiesel). For the objective JCB was mixed with PY (Pyrogallol) and different metal contaminants. JCB samples were stored for 6 months in open air exposed to sunlight. Different properties were checked with respect to time. It was found that stability of fresh JCB was not acceptable as per EN 14214. When PY was mixed with JCB, it stability increased and 200 ppm of PY was sufficient to make fresh and pure JCB stable for almost 6 months. Viscosity (n), PV (peroxide value) and AV (acid value) increased with respect to time. Unsaturated fatty acid composition was also checked with respect to time. From the experiment it was clear that as oxidation deterioration advanced, linoleic and linolenic acid methyl esters decreased and the fraction of oleic acid methyl became relatively high with respect to storage time.
