    摘要: The Benesi-Hildebrand method was used in NMR Spectroscopy to study the hydrogen bonding of iodoform with ten proton acceptors in cyclohexane at 25℃. The values of K's (M¯1) and Δc's (H2) of iodoform systems were determined as followings: N, N-dimethylacetamide, 0.73, 50.5; cyclohexylamine, 0.64, 40.6; cyclohexanone, 0.65, 38.9; cyclopentanone, 0.62, 41.5; 3-pentanone, 0.58, 36.0; acetone, 0.56, 35.0; ethylacetate, 0.51, 32.8; dioxane, 0.54, 31.3; tetrahydrofuran, 0.53, 28.8; diethylether, 0.36, 20.7. The experimental results were discussed. The H-bonding strength decreases in the order as: N, N-dimethylacetamide>cyclohexylamine≈ketone>ester>ether.
