研究萃取剂的化学结构与萃取性能的关系是萃取化学的一个组成部分,它对阐明萃取机理、探讨萃合物的组成与结构以及寻找高效萃取剂都有帮助。文献上有关这类报导多限于中性磷型萃取剂,涉及酸性磷化合物的记载不多。酸性磷(膦)酸酯的酸性强度、位阻效应和溶解度的影响是决定萃取性能的重要因素。我们认为进一步验证这些规律,并探讨它们的
Studying the relationship between chemical structure and extraction performance of extractant is one of the components of extraction chemistry. It is helpful to elucidate extraction mechanism, to explore the composition and structure of extraction complex and to find efficient extraction agent. The literature on this type of reports is mostly limited to neutral phosphorus extractant, involving little acid phosphate compounds. The acid strength, steric hindrance and solubility of acidic phosphorus (phosphonate) esters are the important factors that determine the extraction performance. We think further verifying these laws and discussing them
