A novel solid acid catalyst, sulfonated chloromethyl polystyrene (CP) resin (CP‐SO 3 H‐1.69), was synthesized by partially substituting chlorine groups (Cl) of CP resin with sulfonic group(SO 3 H). This new type solid acid contains not only acid sites, but also cellulose‐binding sites (Cl). A high yield of levulinic acid up to 65.5 % was obtained by converting microcrystalline cellulose over CP‐SO 3 H‐1.69. The high catalytic activity of CP‐SO 3 H‐1.69 was attributed to high amount of sulfonic group and chlorine on the catalyst, which is essential to keep the catalyst with great affinity to substrate.
