摘要： 研究了伯胺N1923萃取醋酸(HAc)的机理。利用对应溶液法确定了萃取平衡,求得平衡常数;辅以饱和法、红外光谱法确认萃合物的组成为N1923·HAc,N1923·2HAc和N1923·3HAc.初步探讨了温度对萃取平衡的影响和进行反萃的条件。

Abstract: The mechanism of extraction of acetic acid with primary amine N1923 has been studied at 298?1 K. The composition of the extracted complexes was determined by methods of the corresponding solution, saturation extraction and infrared spectrometry. The influence of temperature upon the extraction equilibrium has been discussed. The back-extraction of the acetic acid from loading organic phase with NaOH solution has been explored.

Key words: primary amine N1923, extraction, acetic acid, corresponding solution method, infrared spectrometry
