  An efficient and environmentally benign procedure for the catalytic esterification of salicylic acid with aliphatic alcohols, CnH2n+1OH (n = 1-5) and benzylic alcohols, RC6H4CH2OH (R = H, NO2, OCH3, Br, Cl, Me) was developed using nano-SiO2-supported Preyssler heteropolyacid both under thermal conditions and microwave irradiation. Silica nanostructures were obtained through a sol-gel method and were characterized by transmission electron microscopy and powder X-ray diffraction. The effects of various parameters such as solvent type, molar ratio of substrates, Preyssler heteropolyacid loading on silica, catalyst amount, temperature, and reaction time were studied and the optimum conditions were obtained. It has been found that the catalyst with 30 wt% loading is highly active and shows high yields in esterification reactions. The use of nano-SiO2-supported Preyssler heteropolyacid coupled with microwave irradiation allows a solvent-free, rapid (3 mm), and high-yielding reaction. This catalyst can be easily recovered and reused for many times without a significant loss in its activity.

  For the first time, a new water stable BrOnsted acidic ionic liquid based on Keggin heteroployacid (HPA) was used as environmentally benign catalytic medium in the esterfication of salicylic acid with aliphatic alcohols, CnH2n+1OH (n = 1-5) and benzylic alcohols, RC6H4CH2OH (R = H, NO2, OCH3). This ionic liquid (IL) afforded excellent yield in both thermal conditions and microwave irradiation. Maximum yields were observed under microwave irradiation. Different reaction runs were conducted by varying the reaction parameters such as molar ratio of reactants, weight of the IL, and reaction period in order to optimize the reaction. The IL was easily recovered and reused many times. No significant loss in catalytic activity was observed on recycling.
