摘要
本文对有机胺萃取水溶液中柠檬酸的萃合物采用双对数法和连续变量法进行了研究,确定有机胺与柠檬酸萃合物的结构为C_6H_8O_7·2R_3N;对平衡过程的反应变进行了研究,并探讨了萃取反应的热力学现象,经实验表明,有机胺在萃取过程为放热反应。
In this paper the structure-reactivity of extraction of citric acid from the aqueous solutions by organic amine has been proposed. The composition of the extracted complex has been determined by double logarithm method and continued variate method. The thermodynamics phenomena of extraction equilibrium was alse studied.
