Abstract: This work was elaborated for biodiesel and glycerine production and purification since vegetal oils, besides it determinated the kinetic of the vegetal waste frying oils transesterification reaction, mixed with ethanol and NaOH as catalyst into a batch jacket reactor of one liter capacity, the reactor is equipped with a mechanical stirrer, which works at 400 rpm, this information was obtained from previous researches. Furthermore, the investigation was made at several temperatures like 30, 50, 70 and 80 °C and taking samples at different times. Then, they was analyzing by HPSEC (High Performance Size-Exclusion Chromatography). The oil-ethanol molar ratio used was 1:6, this relation showed a good performance according to the esters and glycerol formation. In the next step, excess alcohol was removed by a vacuum distillation route evaporator at 80° C, later two phases separation (esters and glycerol) is getting in a decantation funnel. After that, the esters phase was washed whit acidified water to retire catalyst traces, glycerol, alcohol and other impurities presents in biodiesel, then sodium sulfate is added to remove much water like as possible. Finally, biodiesel is distillated in a molecular distiller. Copyright © 2009, AIDIC Servizi S.r.l.
