研究了10种不同有机溶剂对锌羧酸盐的萃取。通过研究其分布与pH、试剂浓度和溶剂浓度（在惰性介质中）的关系，确定了其种类并估计了萃取常数。假设了物种类型与提取效率之间的相关性。提取4-甲基-2-戊酮、1 -丁醇和4-甲基-2-戊醇的物质为ZnR2S2，提取苯和氯仿的物质为ZnR2(HR)S，提取丁基醚和戊基醚的物质为ZnR2S，提取四氯化碳的物质为ZnR2(HR)，提取己烷和环己烷的物质为ZnR2(H2O)2。式中，R为氧化离子，HR为氧，S为有机溶剂。假设水分子附着在ZnR2S和ZnR2（HR）上，可以解释这种萃取行为。
The extraction of zincoxinate into 10 different organic solvents was investigated. By studying the dependence of the distribution upon pH, reagent concentration, and solvent concentration (in an inert medium), the species were identified and the extraction constants estimated. Correlations between the species type and the efficiency of extraction are postulated. The species extracting into 4-methyl-2-pentanone, I-butanol, and 4-methyl-2-pentanol is ZnR2S2, that extracting into benzene and chloroform is ZnR2(HR)S, that extracting into butyl and pentyl ethers is ZnR2S, that extracting into carbon tetrachloride is ZnR2(HR), and that extracting into hexane and cyclohexane is ZnR2(H2O)2. In these formulas, R is the oxinate ion, HR is oxine, and S is the organic solvent. It is suggested that the extraction behavior can be explained by assuming a water molecule to be attached to the ZnR2S and ZnR2(HR) species.
