已开发出一种磷化膦液体氧化物，其磷化浓度为2.3M，是TOPO溶剂在50℃时可达到的最大浓度的两倍。分配系数增加了2M，其中m与萃取络合物中的磷摩尔浓度有关。苯酚、醋酸和乙醇的m值分别为1.6、1.0和0.9。运动学没有改变。比较了新型萃取剂与异丙醚萃取苯酚的成本。对乙醇的萃取系数和分离因子与其他可能的萃取剂进行了比较。
ABSTRACT A liquid phosphine oxide has been developed with a phosphoryl concentration of 2.3M, twice the maximum that can be reached in TOPO solvents at 50°C. Distribution coefficients are increased by 2m where m relates to mols phosphoryl in the extracting complex. The value of m is 1.6 for phenol, 1.0 for acetic acid and 0.9 for ethanol. Kinetics are unchanged. Costs of extracting phenol with the new extractant and with isopropyl ether are compared. Extraction coefficient and separation factor for ethanol are compared with other potential extractants.
