Preparation of Biodiesel of Undi seed with In-situ Transesterification

The biodiesel fraction from oil content of Undi (Calophyllum innophyllum L.) is found 60-70%. The extraction of oil is a primary step in any biodiesel production system. To escape this step in-situ transesterification method is used in which the Undi seed crush is directly converted into biodiesel with in-situ transesterification which is fatty acid methyl and ethyl ester composition. The single step reaction is eco-friendly as hexane like solvents not have been used for oil extraction. These components of biodiesel were analysed by GC-MS technique.
