Abstract:
A magnetically separable catalyst n-butylpyridinium tetrachloroferrate ([C۴py]FeCl۴) was designed for the removal of trace olefins from aromatic hydrocarbons. The magnetic ionic liquid was prepared via a facile synthetic route and well characterized by FTIR, TGA/DTG, DTA, UV–Visible, and Raman techniques. Then, the effects of different reaction parameters such as molar ratio, reaction temperature, reaction time, and the reusability of the ionicliquid were investigated. It was found that the ionic liquid ([C۴py] FeCl۴) with ۵ wt% of the catalyst at ۷۰ °C for ۱۲ min., exhibited a better performance for olefin removal.The magnetic IL was easily removed from solution using an external magnet, allowing efficiently recovery and without work-up or purification processes.
