Bronsted acidic ionic liquid, N-methyl-2-pyrrolidonium methyl sulfonate ([NMP](+) CH3SO3-) immobilized on MIL-101( Cr) was fabricated by simple impregnation method with a good combination of MIL-101(Cr) and IL species. The worthiness of IL/MIL-101 (Cr), as a Bronsted acid catalyst, has been examined for the esterification of acetic acid with amyl alcohol and Friedel-Crafts acylation of anisole. Our findings demonstrated that IL/MIL-101 (Cr) catalyst exhibited distinct catalytic activity with respect to the other catalysts towards the esterification reaction and Friedel-Crafts acylation of anisole. The Bronsted acidic catalysts loaded on MIL-101(Cr) as a new category of porous materials are probably auspicious heterogeneous catalysts for acid-catalyzed to replace the use of traditional homogeneous catalysts. Furthermore, the catalyst can be easily removed from the reactions mixtures and reuse for posterior reactions, more than six times without any considerable decay in catalytic performance.
