研究了三辛胺萃取羧酸过程的机理,发现该过程中稀释剂的影响十分显著,在不同的稀释剂中三辛胺萃取羧酸的分配比相差三十至七十倍。其萃取能力与三辛胺的浓度和稀释剂的性质有关。萃取剂浓度一定时,取决于萃合物与稀释剂的相互作用能力及其在稀释剂中的疏溶作用。相互作用能力越强,疏溶作用越弱,越有利于革取。 The mechanism of the extraction of carboxylic acid by trioctylamine was studied. The effect of diluent was found to be significant. The distribution ratio of trioctylamine to carboxylic acid in different diluents was thirty to seventy times worse. Its extraction capacity and the concentration of trioctylamine and diluent properties. When the extractant concentration is constant, it depends on the ability of the extract to interact with the diluent and its solubility in the diluent. The stronger the interaction ability, the weaker the role of sparse, the more conducive to leather.
