To avoid the conflict between food security and biodiesel production; second generation biofuel has drawn much attention. From this sense, Jatropha curcus is widely considered as an ideal feed stock of biodiesel production. The properties of Jatropha crop and Jatropha oil are main consideration of policymakers to persuade Jatropha as a potential cradle of biodiesel. This paper deals the various physical-chemical and biological properties of Jatropha oil with environmental impact. Comparison between palm oil, soybean oil and canola oil has also discussed. The major properties highlighted are kinematic viscosity, calorific value, flash point, yield rate, productive life and GHG emission.
