The invention discloses a method for preparing low condensation point biodiesel from high acid value oil. Animal and vegetable oils with the acid value higher than 80mgKOH/g serving as a raw material and mixed alcohol of methanol, ethanol and isopropanol undergo esterification and interesterification two-step reaction to prepare the low condensation point biodiesel. The intersolubiltiy of the oil and the methanol is improved by the ethanol so as to promote the methyl esterification reaction; meanwhile, the product contains a small amount of fatty acid ethyl esters, and new solid catalysts of tungsten molybdophosphate and phosphotungstic acidesterification replace concentrated sulfuric acid in the esterification reaction; and in the interesterification reaction, the ethanol and the isopropanol promote the conversion of glyceride, and simultaneously the product contains partial fatty acid ethyl esters and branched-chain aliphatic esters. Therefore, the reaction is easy to carry out, the cold flow properties of the biodiesel can be improved and the condensation point of the biodiesel can be reduced.

This invention comprises the use of the interesterification reaction between vegetal or animal oils as monoacid esters (preferentially with 1 to 12 carbons) and monoalcohol esters (preferentially with 1 to 12 carbons). The use of ethyl acetate is preferred as it is a product that may be obtained from ethanol (renewable) and has a boiling point (77 deg. C.), which facilitates separation by vacuum distillation at the end of the reaction and its reuse. By varying the molar ratio between glycerol triester (oil or fat) and monoalcohol ester, different proportions of glycerol esters are obtained with 1 or 2 linked fatty acids and 1 or 2 linked acids of short chain, along with the formation of fatty acid ester and monoalcohol ester. After the distillation of excess residual ethyl acetate, products are obtained with viscosity from 21 to 33 cPs at 25 deg. C., in the case of the reaction with soy oil.
