| Abstract: |
| The fatty acid ethyl ester was prepared by alkali catalysis from chia seed oil. The catalytic effects of sodium methoxide, sodium ethoxide and NaOH were evaluated,then the preparation conditions of fatty acid ethyl ester were optimized by single factor experiment and orthogonal experiment. The results showed that the conversion rate and yield of fatty acid ethyl ester were the highest using NaOH as catalyst, and the optimal preparation conditions were obtained as follows： transesterification temperature 80 ℃, transesterification time 1.5 h, molar ratio of anhydrous ethanol to chia seed oil 9∶ 1, and the dosage of NaOH 0.6% (based on the oil mass). Under these conditions, the conversion rate of the chia seed oil fatty acid ethyl ester could reach 89.01%. |
