%X Using methyl acetate as acyl acceptor instead of methanol, enzyme-catalyst was saved from the harm of methanol and glycerol. In this work, biodiesel purification process of methyl acetate reaction system was carded out. Moreover, feasible operation parameters and material balance were also obtained based on the results of purification experiments. The final end-product, refined biodiesel, could meet the strict criterion of DINE 51606. The vacuum rectification of crude biodiesel was analyzed by simulation software Pro/If to assess the influential factors on it. The computing results showed that the preferred operation parameters of the vacuum rectification column would be in the ranges of 9-11 pieces of theoretical trays, 133-1333 Pa at the top of distillation column and 1.5-3.0 of the reflux ratio.
