- Abstract:
-
In this paper, the extraction of citric acid from aqueous solution by organic amine was investigated by double logarithmic method and continuous variable method, and the structure of organic amine extracted with citric acid was determined to be C_6H_8O_7-2R_3N; the reactive change of the equilibrium process was investigated, and the thermodynamic phenomena of the extraction reaction were discussed, which was experimentally shown to be an exothermic reaction in the process of the organic amine.
