This ionic liquid 1-methyl-3-[(triethoxysilyl)propyl]imidazolium chloride (TMICl) is immobilized on Mechanically activated Fly Ash (MFA) by co-condensation method to develop an active organocatalyst (TMICl/MFA). The mechanical activation has generated significant number of silanol groups suitable for immobilizing ionic liquids. For characterization of various materials, different techniques viz, XRD, FTIR, SEM-EDX, TGA, BET surface area, H1NMR are used. The prepared TMICl/MFA exhibited high catalytic activity for a series of microwave assisted esterification of aliphatic alcohols and salicylic acid for four successive reaction cycles under optimized conditions.}, keywords = {1-methyl-3-[(triethoxysilyl)propyl]imidazolium chloride,solid catalyst,Microwave irradiation,MFA,Esterification,co-condensation}, url = {https://ijcce.ac.ir/article_30934.html}, eprint = {https://ijcce.ac.ir/article_30934_cbee08ea3eaf40c16b7772b682e619c5.pdf} }
