Abstract

The invention discloses a method for preparing cobalt octoate by using LiCoO, an anode material of a waste lithium battery, comprising the following steps: carrying out acidolysis on powder of the LiCoO, the anode material of the waste lithium battery by chemical extraction and back extraction, removing Fe and Al by chemical precipitation, filter pressing and deslagging, adding P204 self-made auxiliary extractant to remove impurities and adding P507 self-made auxiliary extractant to extract and separate Co from Li to prepare CoSO4 liquid with content of 75-80%, precipitating raffinate to prepare LiCO3 with primary deposition rate more than 75%, carrying out double decomposition reaction on sodium octoate obtained after saponification reaction between the prepared CoSO4 liquid and octoic acid as well as sodium hydroxide and preparing the product of cobalt octoate liquid through washing, standing to be layered, dehydrating, regulating metal contents and filtering. The rate of recovery of cobalt from the powder of the LiCoO, the anode material of the waste lithium battery is more than 97%.

Description

technical field

[0001] The present invention relates to a method for preparing cobalt isooctanoate, more specifically relates to a method for preparing cobalt isooctanoate by using lithium cobaltate at the positive electrode of waste lithium batteries, which is suitable for preparing cobalt isooctanoate by utilizing lithium cobaltate at the positive electrode of waste lithium batteries . Background technique

[0002] Cobalt Octoate, English name: Cobalt Octoate, molecular formula: 2(C 8 h 15 o 2 )·CoO chemical structure formula: Red-purple viscous homogeneous liquid. Insoluble in water, slightly soluble in ethanol, soluble in ether.

[0003] Cobalt isooctanoate is widely used in coatings, ink driers, unsaturated polyester resin accelerators, crosslinking agents, catalysts, plastic stabilizers and organic synthesis of phenylacetic acid and acetophenone.

[0004] At present, the production of cobalt isooctanoate (liquid type) usually has the following three methods. Me...
