本文用气液色谱法研究了 Ni[(C_8H_(17)O)_2PS_2]_2与 C_1—C_4伯醇加合反应的热力学性质.测定了317—353K 范围内加合反应的平衡常数,用作图法求得反应的ΔH和ΔS.ΔH、ΔS 与伯醇的碳原子数之间呈线性关系:-ΔH=11.8+4.57X (kJ/mol)-ΔS=30.6+16.4X (J/mol·K)用静电作用模型描述了加合物成键的实质.加合反应的平衡常数可以用经验公式描述:lgK=-1.601-0.8572X+(619.1-237.8X)/T
In this paper, the thermodynamic properties of the adduct reaction of Ni [(C_8H_ (17) O) _2PS_2] _2 with C_1-C_4 primary alcohol have been investigated by gas-liquid chromatography. The equilibrium constant of the addition reaction in the range of 317-353 K has been measured, ΔH and ΔS.ΔH, ΔS and the number of carbon atoms of the primary alcohol have a linear relationship: -ΔH = 11.8 + 4.57X (kJ / mol) -ΔS = 30.6 + 16.4X (J / mol · K ) Describes the nature of the adduct bond using the electrostatic interaction model. The equilibrium constant of the adduct reaction can be described empirically: lgK = -1.601-0.8572X + (619.1-237.8X) / T
