**5.2 Continuous transesterification by reactive distillation for synthesis of biodiesel**

The process parameters studied here are alcohol-to-oil ratio.{3:1, 6:1 and 9:1 ,Optimum methanol-to-oil molar ratio =6:1},Reaction time {Residence time of 2min, 3min., 6min, optimum residence time = 3min},Temperature {55, 60, 65oC, Optimum temperature = 65oC }, catalyst loading (1,1.5 and 2 % by wt of oil).
