Abstract :

O–acetylation of salicylic acid has been carried out under solvent–free conditions using protonated zeolites (Hβ, HZSM–5and HY) and these platinated forms (Pt–Hβ, Pt–HZSM–5& Pt–HY) as solid acid catalysts to synthesize acetyl salicylic acid. The process has simpler work up procedure and the catalyst has been successfully recovered and recycled. The zeolite catalysts have been characterized by different techniques like BET surface area measurement, total acidity by NH3– TPD/ n–butylamine back titration method and crystallinity by powder X–ray diffraction. O–acetylation using platinated zeolite catalysts under was found to be an efficient and environment friendly (green) process. Platinated zeolites were found to be much more effective, reusable, recyclable, and green catalysts for the synthesis of acetyl salicylic acid when compare to protonated zeolites.
