Embodiment 1

[0064] The present embodiment provides a kind of preparation method of copper octanoate, comprises the following steps:

[0065] 1) Take 20ml octanoic acid and place it in a 250mL three-necked flask, add water to twice the volume of the acid, heat and stir at 30°C for 30min in a water bath to prepare the first solution.

[0066] 2) Prepare a sodium hydroxide solution, add the sodium hydroxide solution to the first solution, raise the temperature to 55° C., stir and react for 30 minutes to obtain the second solution.

[0067] 3) Distill 90% of the water in the second solution.

[0068] 4) Then add 50ml of 120# organic oil, shake well, slowly add copper sulfate feed solution dropwise, and react for 2 hours.

[0069] 5) Transfer the liquid to a 250mL separatory funnel, and let stand to separate layers. Then carry out the liquid separation operation, take the upper layer solution, wash 3 times with 95 ℃ hot water, the volume of hot water is 2 times of the organic phase volume. ...

Embodiment 2

[0072] The present embodiment provides a kind of preparation method of copper octanoate, comprises the following steps:

Abstract

The invention relates to the field of material preparation, and particularly relates to a copper octanoate preparing method and a copper octanoate product. The method includes adding solvent oil and acopper sulfate solution into a first solution, reacting the mixture for 2-6 h to obtain a second solution, subjecting the second solution to liquid separation and washing, and then performing distillation to remove an organic phase, wherein the first solution is obtained by reacting an octanoic acid solution and a sodium hydroxide solution or the first solution is a sodium octanoate solution, andthe mole ratio of the octanoic acid to the sodium hydroxide in the first solution is 0.5-2.0. The method is simple to operate and high in feasibility. The prepared copper octanoate has good properties. The copper octanoate product prepared by the method has good properties.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a method for preparing copper octoate and a copper octoate product. Background technique [0002] Copper octanoate, relative molecular mass is 349.96, molecular formula: (C8H15COO)2Cu, CAS number 20543-04-8. [0003] Copper octoate has a wide range of applications. Specifically, copper octoate is widely used in coatings, preservatives, cable waterproofing agents, bactericides, bactericides, algaecides, and the like. [0004] The preparation method of copper octanoate in the prior art is relatively complicated.
