摘要
气液色谱法是研究酸碱相互作用热力学性质的有效方法之一,适合于气液表面化学反应的研究,可以得到一些用其它方法难以获得的热力学参数,丰富了表面化学领域的研究,具有重要的理论意义和应用价值。文献利用气液色谱法测量了Ni[THDD]_2,Ni[(C_8H_(17)O)_2PS_2]_2与含氮、含氧的有机碱加合反应的平衡常数,
The GLC study on the thermodynamic properties of adduct formation between Ni-C (C8H17O)2PS2) 2 and carbonitrile is presented.The equilibrium constants in the range of 333.2-363.2K were determined and described by the empirical equation:lgK=-0.8697-0.6719nc+(515.7+179.9nc)/TAH and AS were calculated by the least square method.It was found that-ΔH and-ΔS increased linearly with the number of carbon in carbonitrile moleculesΔH=9.88+3.45nc(KJ/mol) ΔS=16.65+12.87nc(J/K·mol)The nature of adduct bonds was explained by means of electro-static model.
