摘要
合成了一系列双子型酸性离子液体,该类型离子液体以乙二铵为连接链,由碳链长度可调的双子型阳离子与不同的阴离子组成.因此,具有相分离催化剂的性质,并应用于高级脂肪酸与醇的酯化反应,以合成生物柴油.详细考察了各参数的影响.结果表明,[C12Sb][p-CH3C6H4SO3]表现出高催化活性及可重复使用性能.
Quaternary ammonium BrSnsted acid surfactant-combined dicationic ionic liquids （BASDILs） based on zwitterionic 1,2-bis[N-methyl-N-（3-sulfopropyl）-alkylammonium]ethane betaines and various anions were prepared and characterized. BASDILs possess properties similar to those of phase-separated catalysts and were applied to the catalytic synthesis of biodiesel from free fatty acids and alcohols. Several factors were investigated and the results indicated that [C12Sb][p-CH3C6H4SO3] was the optimal catalyst, with good catalytic performance and reusability under mild conditions.
