Widely used poly(ethylene terephthalate) (PET) material induces environmental concern on its wastes. In this paper, different 1-hexyl-3-methylimidazolium (Hmim) halometallates, including [Hmim]ZnCl 3 , [Hmim]CoCl 3 , [Hmim]FeCl 4 and [Hmim]CuCl 3 , are synthesized as Lewis acidic ionic liquids (LAIL...
