Abstract
1-Ethyl-3-methylimidazolium acetate ([C2mim]OAc) is the most commonly used cellulose-dissolving ionic liquid and has been extensively studied for biorefinery applications. Although [C2mim]OAc had been considered to be a liquid, we here found [C2mim]OAc crystals at room temperature (around 25 °C) with a melting point of 44 °C. A plausible reason for the crystallization is shearing stress. [C2mim]OAc seed crystals led to the crystallization of liquid [C2mim]OAc.
