Estry metylowe kwasów tłuszczowych jako substytut olejów napędowych. Część 1, Kinetyka reakcji transestryfikacji triglicerydów olejów roślinnych metanolem

Transestrification of soybean oil with methanol is presented. Three stepwise and reversible reactions are belived to occur. The effect of variations in mixing intensity (Reynolds Number = 3100 to 12400) and temperature (25°C to 70°C) on the rate of reaction were studied while molar ratio of alkohol to triglycerol (6:1) and the concentracionof catalyst 0,2 wt% based on soybean oil were held constant. The variations in mixing intensity appear to effect the reaction parallel to the variations in temperature. A reaction mechanism consisting of an initial mass-transfer-controlled region followed by a kinetically cintrolled region is showed.
