A new neodecanoic acid-isonicotinic acid n-octyl ester synergistic extraction system, method and application

By introducing isonicotinic acid n-octyl ester as a synergist into the neodecanoic acid system, the problem of separating manganese from impurity ions in the neodecanoic acid system was solved, realizing an efficient and simplified manganese extraction process, which is suitable for the production of high-purity manganese salt products.

Abstract

本申请提供一种新癸酸‑异烟酸正辛酯协同萃取体系、方法及应用。所述协同萃取体系包含新癸酸、异烟酸正辛酯和稀释剂，其中新癸酸与异烟酸正辛酯的摩尔比为1:0.5～1:1.5。使用该体系从含锰硫酸盐溶液中提取锰时，有机相在与水相接触前不进行预皂化处理。与单独使用新癸酸相比，本发明协同萃取体系在不预皂化条件下显著提高了锰的萃取率，同时改善了锰与镁、钙等杂质离子的综合分离选择性，并有效减轻了萃取过程中的乳化倾向，改善了分相性能。
