Here we show that the ball milling pretreatment could markedly facilitate the conversion of microcrystalline cellulose to HMF by titanyl sulfate (TiOSO 4). The ball milling pretreatment remarkably decreases the degree of crystallinity of microcrystalline cellulose with a reduction of molecular weight via disrupting the hydrogen bond and partially breaking the β-1,4 …
