Abstract: The present invention relates to a process for monitoring the catalytic activity of an ionic liquid and for the regeneration of the ionic liquid in continuous conversion of an olefin in an alkylation. The process includes (a) providing an ionic liquid; (b) reacting a hydrocarbon mixture with the ionic liquid to obtain an ionic liquid phase. In step (d), adding an organic compound to the ionic liquid phase. In step (e), obtaining an absorption peak of a mixture from step (d) and in step (f) repeating until the absorption peak reaches a maximum or a minimum value. In step (g), determining the total amount of the organic compound or the ionic liquid phase added. Next, (h) calculating the catalytic activity of the ionic liquid. Then, (i) adding aluminium halides to the reaction of step (b) such that the activity of step (h) stays above the minimum level.

Abstract: The present invention relates to a process for monitoring the catalytic activity of an ionic liquid. In step (a), providing an acidic ionic liquid; (b) providing an organic compound; (c) adding at least a portion of the organic compound to at least a portion of the ionic liquid; (d) recording an infrared spectrum of a mixture from step (c) to obtain at least one absorption peak. In step (e), repeating steps (c) and (d) until at least one absorption peak reaches a maximum value or a minimum value. In step (f), determining at the maximum value or minimum value of step (e): the total amount of the organic compound or the total amount of the ionic liquid added. In step (g), calculating the catalytic activity of the ionic liquid based on: the total amount of the organic compound or the total amount of ionic liquid, as determined in step (f).
