The ionic liquids with the strongest ionic activity were characterized by nuclear magnetic resonance. With the ionic liquid as catalyst, the reaction conditions of triolein model were optimized by single factor experiment, and on this basis, the process conditions for preparing biodiesel from fried waste oil were optimized by orthogonal experiment. The biodiesel was characterized by infrared spectroscopy and nuclear magnetic resonance. The results showed that C5MSS showed the strongest catalytic performance. Under the conditions of molar ratio of methanol to oil 18∶ 1, reaction time 8 h, reaction temperature 100 ℃, and ionic liquid dosage 8%(based on the triolein mass), the yield of methyl oleate was 91.18%, and the yield of methyl oleate could still reach more than 83% after the ionic liquid was reused for seven times. The optimal process conditions for preparing biodiesel from fried waste oil were obtained as follows: molar ratio of methanol to oil 18∶ 1, reaction temperature 80 ℃, reaction time 9 h, and catalyst dosage 10% (based on the mass of fried waste oil). Under these conditions, the yield of biodiesel could reach 98.60%.The characterization results of infrared spectroscopy and nuclear magnetic resonance showed that fatty acid methyl esters were produced by the reaction, and the transesterification reaction was relatively thorough.
