在298.15K下用连续稀释膨胀计或振动管密度计测量了二甲基甲酰胺(DMF),二甲基乙酰胺(DMA),N-甲基吡咯烷酮(NMP),γ-丁内酯(γ-BL),二甲基亚砜(DMSO)分别与四氯化碳和三氯甲烷构成的二元系的过量体积.除DMSO+CHCl_2二元系的V~(E-x)曲线为S形外,其余二元系的V~E值均为负值.在所研究的两个系列中,|V_(...
under nitrogen atmosphere, and performed in an oven-dried or flame-dried apparatus using anhydrous solvents, which were degassed under reduced pressure, then purged with argon and dried over activated molecular sieves (3 Å), prior to being sealed and transferred to the glovebox. All solvent ...
