1H NMR, 13C NMR, and 13C spin-lattice relaxation time(T1) of the mixtures of room temperature ionic liquid [C8mim][BF4] and acetone with different proportions have been studied by NMR. The results indicated that the interaction between the protons of the ring, the methyl and methylene next to the nitrogen of ionic liquids and the carbonyl oxygen of acetone weakened the strong interaction between the cation and anion of the ionic liquid, thus increased the motion and decreased the viscosity of the ionic liquid.
