Preliminary study on extraction and synthesis of biodiesel from jatropha curcas seeds and soybean

Solvent extraction with hexane has been evaluated for extraction of oil from Jatropha curcas L. seeds and soybean. Experimentally, the effects of time, temperature and size on the extraction yield were investigated. It was found that oil extraction with hexane has high efficiency, while the extracti...
