摘要
用滴定微量量热法研究了伯胺N192 3萃取柠檬酸的过程 ,测定了萃取体系在不同温度时的热功率 -时间曲线 ,确定了萃取过程的反应热。按照化学平衡原理 ,利用反应热和萃取平衡常数 ,计算了不同温度下的热力学函数ΔrHσm,ΔrGσm。
The extraction of citric acid with primary amine N 1923 was studied using the titrameter microcalorimetric method. We determined reaction processes produce heat from the power time curves at different temperatures and identified heat of reaction. According to the chemical equilibrium theory, using the heat of reaction and extraction equilibrium constant, thermodynamical function ΔrH σ m,ΔrG σ m,ΔrS σ m at different temperatures were calculated.
