The chloromethylation of MIL‐101(Cr) was achieved via pre‐synthesis modification approach starting from p ‐xylene as starting material, for the first time. A low‐cost three‐step procedure including chloromethylation of p ‐xylene, oxidation of chloromethylated p ‐xylene to form chloromethylated terephthalic acid and hydrothermal formation of metal organic framework was applied to synthesize chloromethylated MIL‐101(Cr). The main advantage of this new protocol is the elimination of methoxyacetyl chloride as an expensive reagent which was previously used for the chloromethylation step. Different techniques including nuclear magnetic resonance (NMR) spectroscopy, GC‐Mass analysis, X‐ray diffraction (XRD), FTIR, field emission scanning electron microscopy (FE‐SEM) and N 2 sorption measurement confirmed the successful formation of MIL‐101(Cr) and chloromethylated MIL‐101(Cr).
