Keshavarz, Mosadegh published the artcileNovel SO3H-functionalized polyoxometalate-based ionic liquids as highly efficient catalysts for esterification reaction, Related Products of esters-buliding-blocks, the main research area is sulfonic acid functionalized phosphotungstate ionic liquid preparation thermal stability; carboxylic acid aliphatic alc ionic liquid catalyst esterification; ester preparation.
Three novel heteropolyanion-based Bronsted acidic ionic liquids (BAILs) (PhBs1)3PW, [PipBs1]3PW and [PipBs2]3(PW)2 [PW = PW12O403-; PhBs1 = 4-(1,10-phenanthrolinium)butanesulfonic acid; PipBs1 = 4-(1,4-dimethylpiperazinium)butanesulfonic acid; PipBs2 = 1,4-(1,4-dimethylpiperazinium)bis(butanesulfonic acid)] were synthesized and characterized using FTIR, 1H and 13C NMR, electrospray ionization mass spectrometry, elemental anal., EDX and TG anal. techniques. The esterification reactions of monocarboxylic acids with monohydric alcs. were carried out using these catalysts. After reactions, the catalysts can be readily recovered by decantation or filtration and reused up to 6 times without significant loss of activity. Moreover, bis(sulfoacid)-functionalized 1,4-dimethylpiperazinium phosphotungstate [PipBs2]3(PW)2 showed the best catalytic performance among the prepared catalysts for the esterification reaction.
