摘要：

H-1 NMR of aqueous N,N-dimethylacetarnide (DMA) solutions was measured at different temperatures. Based on chemical association model, the association equilibrium constant K and the corresponding Delta H were obtained. In addition, these results were compared with those of aqueous dimethylformamide and N-methylacetamide solutions. It was found that the effect of the amides on the structure of water was very dependent upon solution composition and the intrinsic molecular structure of the amide.
