Thermodynamic Excess

By analyzing the cooling curves and the resulting melting point diagrams of the chloromethylsilane- pyridazine and pyrazine systems the existence of the incongruently melting addition compounds CH3SiCl3 • Pyridazine, (CH3)2SiCl2 • (Pyridazine)2, (CH3)3SiCl • (Pyridazine)2, CH3SiCl3 • (Pyrazine)2, (CH3)2SiCl2 • (Pyrazine)2 , (CH3)3SiCl • (Pyrazine)2 was proved. By electro-optical measurements of the turbidity point it was proved that the system (CH3)3SiCl- Pyridazine exhibits a miscibility gap which intersects the liquidus curve of the amine. Based on certain approximations it was possible to fit thermodynamic functions to the experimental results to obtain the excess data of mixing of the corresponding systems. These data allow for a more profound understanding of the Lewis-acid base behaviour of the silanes and amines.Chloromethylsilanes, Pyridazine, Pyrazine, Phase Diagrams, Addition Compounds, Thermodynamic Excess Functions

Excess volumes of the binary mixtures, benzene + benzonitrile, benzene+ diethyl ketone and toluene+diethyl ketone, were determined at 303.15 K. The VE data and HE data of the mixtures reported in the literature were analysed in the light of both the original and modified forms of the Flory theory. The analysis showed that the modified Flory theory correctly predicts the sign of the excess functions over the whole range of composition when the single interaction parameter of the theory is treated as an energy parameter.
