摘要: The excess molar enthalpies of 8 binary mixtures for the o-, m-, and p-isomers fluoroiodobenzene, fluoromethoxybenzene, bromofluorobenzene, chlorofluoro-benzene, difluorobenzene, fluoromethylbenzene, fluoronitrobenzene, aminofluoro-benzene were measured at 298.15 K. changes very small. experimental results revealed that isomers containing two electron-acceptor groups showed most positive enthalpy change, while both one electron donor acceptor group, such as aminofluorobenzene, more stable always negative results.
