(57)    Abstract

The present invention relates to an improved process for the preparation of biodiesel from triglyceride oils through transesterification. More specifically, the invention relates to preparation of fatty acid methyl ester of oil mechanically expelled from whole seeds of Jatropha curcas, a plant that has potential for cultivation on wasteland in India and other countries. All the unit operations in the process for preparation of Biodiesel are carried out at ambient temperature. The utilization of the co products for preparing value added products and the integrated approach to utilize and manage the effluent streams make the process environmentally friendly. The process steps

for work up of the crude methyl ester are made simple, practical, effective and economical to prepare Biodiesel in high yield and to match international
