【摘要】 通过吗啡啉与癸酰氯反应生成了酰胺类萃取剂N-癸酰吗啡啉(DMPHL),并用苯为稀释剂考察DMPHL萃取苯酚的性能。研究了萃取剂浓度、苯酚浓度、酸度和温度对萃取苯酚的影响,计算出萃取反应的平衡常数以及有关的热力学函数,实验结果表明,DMPHL对于苯酚有良好的萃取性能。更多还原

【Abstract】 The extraction of phenol in water by _N-decanoylmorpholine （DMPHL） was carried out satisfactorily. The dependence of the extraction distribution ratio on the concentration of the extractant and phenol, acidity and temperature was investigated. The composition of the extraction complex was identified to be C₆H₅OH·DMPHL, and the related thermodynamic functions were evaluated. The IR spectra showed the presence of intermolecular hydrogen bonding between phenol and DMPHL in the extraction complex.更多还原
