Catalytic performance of supported Preyssler and Keggin heteropolyacids on silica, H14[NaP5W30O110]/SiO2 and H3[PW12O40]/SiO2, have been studied at room temperature for highly selective and rapid liquid-phase O-acetylation of salicylic acid in order to synthesize acetylsalicylic acid which is well-known century-old chemical pharmaceutical. The usual catalysts in acetylsalicylic acid synthesis are toxic liquid acids such as HNO3 and H2SO4, which would cause serious corrosive and other environmental problems. The performance of silica-supported preyssler and Keggin with various loadings is compared with sulfuric acid method. The heteropolyacids show almost 25% more activity compared with H2SO4.
