摘要	Bronsted-Lewis acidic ionic liquids 1-(3-sulfoilic acid)-propyl-3-methylimidazole chlorozincinates ([HO(3)S-(CH(2))(3)-mim]Cl-ZnCl(2)) were synthesized and characterized. The characterization results indicated that [HO(3)S-(CH(2))(3)-mim]Cl-ZnCl(2) (molar fraction of ZnCl(2) x > 0.5) had both Bronsted and Lewis acid properties. The catalytic properties of these ionic liquids were investigated using the dimerization of rosin, and it was shown that ionic liquid [HO(3)S-(CH(2))(3)-mim]Cl-ZnCl(2) (x = 0.64) was a good catalyst. Under the optimum conditions for polymerization, i.e., rosin 5.0 g, toluene 15 g, the mass fraction of ionic liquid 5%, reaction temperature 110 degrees C, and reaction time 4 h, a product with the softening point of 118 degrees C was obtained. It was also found that the product was easily separated from the reaction mixture and the ionic liquid catalyst had good reusability.
