The use of lipases in reactions of transformation of vegetable oil is against the principles of green chemistry, mainly because they are renewable and have a high efficiency and specificity in oleochemical reactions. Among the lipases studied stands out mainly Candida antarctica B (Novozym ® 435) and being marketed already immobilized in support of acrylic resin, has the advantage of being reused in the reactions. It was possible to optimize a system of transesterification by a continuous process, with which it was possible maximum conversion of substrate (sunflower oil) in ethyl esters, and perform 87 cycles with the same enzyme without reducing the activity and 224 cycles, after the reduction of the activity. The system obtained are adequate to objectives and can be used in absence of organic solvent, it is only need the alcohol excess.Downloads
