摘要：

A novel basic ionic liquid paired by 1-butyl-3-methyl-morpholine cation and morpholine anion ([Hnmm]Im) was synthesized in two steps; the structure of ionic liquid intermediates was characterized by 1H-NMR and FT-IR. The alkaline ionic liquid was obtained through anion exchange and used as catalyst in the synthesis of biodiesel by transesterification. The results showed that the alkaline ionic liquid [Hnmm]Im is highly active as a catalyst in the transesterification; under the optimum reaction conditions of 60°C, [Hnmm]Im amount of 3%, and methanol/oil mol ratio of 6.5:1.0, the content of fatty acid methyl ester (FAME) in the product reaches 95.80% after reaction for 2 h. Moreover, the alkaline ionic liquid exhibits high catalytic stability upon reusage; it remains highly active even after being reused for five times.
