摘要：

Dependence of physicochemical properties of N',N'-dialkylhydrazides of aliphatic carboxylic acids (solubility in kerosene, acid-base properties) on the length of hydrocarbon radicals in the functional group was studied. The extraction capacity for copper(II) salts in weakly acid and ammonia media was examined in the range from pH 5-11 to a NH3 content of 2.7 M. The capacity of the organic phase for copper(II) and re-extraction conditions were determined for the example of N',N'-dibutylhydrazide of octanoic acid.
