Example Embodiment
[0063] Example 1
[0064] This embodiment provides a method for preparing copper octoate, which includes the following steps:
[0065] 1) Put 20ml of caprylic acid in a 250ml three-necked flask, add water to 2 times the volume of the acid, and heat and stir at 30°C for 30min under the heating condition of a water bath to prepare the first solution.
[0066] 2) Prepare the 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 out 90% of the water in the second solution.
[0068] 4) Then add 50ml 120# organic oil, shake well, slowly add copper sulfate feed liquid dropwise, and react for 2h.
[0069] 5) Transfer the liquid to a 250mL separatory funnel, and let stand for layering. Then perform liquid separation operation, take the upper layer solution, wash with 95°C hot water 3 times, the volume of the hot water is twice the volume of the organic p...
