摘要

1-乙基-3-甲基咪唑醋酸酯（[C2mim]OAc）是最常用的纤维素溶解离子液体，在生物精炼应用方面已被广泛研究。虽然[C2mim]OAc 一直被认为是一种液体，但我们在这里发现[C2mim]OAc 在室温（约 25 °C）下呈晶体状，熔点为 44 °C。结晶的一个合理原因是剪切应力。[C2mim]OAc 种子晶体导致液态 [C2mim]OAc 结晶。

Room-temperature [C2mim]OAc crystal

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.
