Rubber seed oil is a potential source for b iodiesel production. Present work focuses on oil ext raction fro m rubber seed by mechanical p ressing method and kinetic study of acid esterification process. Rubber seeds were deshelled, dried, crushed and pressed in a mechanical press. The effect of certain parameters drying temperature, dry ing time, pressing time and pressure were analysed through Design of Experiment methodology. The kinetics of the esterification of free fatty acids (FFA) in

The experimental results were found to fit a first-order kinetic law for the forward reaction and a second -order one for the reverse reaction.
