Designing ionic liquids with dual lewis basic sitesto efficiently separate phenolic compounds from low-temperature coaltar... In the presentwork, three ionic liquids (ILs) with dual Lewis basic sites were designedand synthesized by neutralizating 1,1,3,3-tetramethylguanidine (TMG)and corresponding acids (L-proline, acetate acid,and tetrafluoroboric acid), which were employed to separate phenoliccompounds from the model oil and coal tar....
