摘要 离子液体在催化过程中的应用越来越广泛,而酸性离子液体的酸性是其最重要的物性指标。本文采用UV—Vis谱对溶有Bronsted酸的对水稳定的离子液体的酸强度进行了测定并用Hammett指数来表示Brφnsted酸强度,获得了令人满意的结果。该方法可为催化剂的改进与催化机理研究提供重要的基础实验数据。 The use of ionic liquids is becoming more and more widespread in catalysis. But the acidity of ionic liquids is the best important property. The acid intensity of Brφnsted acidie ionic liquids in stable water was determined by UV - Vis, and through Hamment function, the result was satisfied. The method could provide important basis of the experimental data to the catalyzer improvement and mechanism.
