Abstract
A series of task-specific ionic liquids(TSILs) with the imidazolium and pyridinium that bear an alkane sulfonic acid group were synthesized.The synthesis of benzyl octanoate using benzil alcohol and octanoic acid as reactants,and these TSILs as catalyst was investigated.Effects of the anion and cation of TSILs on their catalytic performance was also investigated.The results showed that the conversion of octanoic acid reached 95.3% by using [PSPy]HSO4 as the catalyst under the conditions of n(octanoic acid):n(benzil alcohol)=1:1.5,molar fraction is 20% of octanoic acid for TSILs,120 ℃ and 2.5 h.In addition,the [PSPy]HSO4 exhibited excellent stability and catalytic activity.The catalyst could be reused ten times without considerable loss of activity and still had a conversion of 94.2%.
