    • The present invention relates to a process for monitoring the catalytic activity of an ionic liquid, comprising the steps of : (a) providing an acidic ionic liquid; (b) providing an organic compound which contains a nitrogen group, oxygen group and/or sulphur group; (c) adding a portion of the organic compound to a sample of the ionic liquid or adding a portion of the ionic liquid to a sample of the organic compound; (d) recording an infrared spectrum of a mixture as obtained in step (c) to obtain at least one absorption peak; (e) repeating steps (c) and (d) until at least one absorption peak obtained in step (d) reaches a maximum value or a minimum value; (f) determining at the maximum value or minimum value of the absorption peak of step (e) : the total amount of the organic compound added in portions to the sample of the ionic liquid or determining the total amount of the ionic liquid added in portions to the sample of organic compound; (g) calculating the catalytic activity of the ionic liquid on the basis of: the total amount of the organic compound added in portions as determined in step (f) or the total amount of ionic liquid added in portions as determined in step (f).
    • 本发明涉及一种用于监测离子液体的催化活性的方法,包括以下步骤:(a)提供酸性离子液体; (b)提供含有氮基,氧基和/或硫基的有机化合物; (c)将一部分有机化合物加入到离子液体的样品中,或者将一部分离子液体加入到有机化合物样品中; (d)记录步骤(c)中得到的混合物的红外光谱,得到至少一个吸收峰; (e)重复步骤(c)和(d),直到在步骤(d)中获得的至少一个吸收峰达到最大值或最小值; (f)确定步骤(e)的吸收峰的最大值或最小值:部分地添加到离子液体的样品中的有机化合物的总量或确定部分加入的离子液体的总量 对有机化合物的样品; (g)基于以下步骤计算离子液体的催化活性:基于步骤(f)中测定的部分添加的有机化合物的总量或步骤(f)中测定的部分添加的离子液体的总量, 。
