Benefits of technology

This new technology makes it possible to prepare pure Cu(NO3)2 without any impurities that could affect its quality or performance. It uses only two steps - making sure everything works properly at all stages – resulting in more efficient manufacturing processes compared to previous methods.

Problems solved by technology

The technical problem addressed in this patents relating to making small particles (such as nanoparticles) from basic coppric acid is that current methods require expensive or complicated processes due to their instability during storage overtime. This results in increased costs compared to producing these tiny objects directly through conventional techniques like precipitation or solvent extraction.

Embodiment 1

[0025] Example 1: Prepare 40ml of copper nitrate aqueous solution with a concentration of 0.75mol / L at normal temperature, add 30mL of 1,3-propylenediamine aqueous solution with a concentration of 0.012mol / L to it under stirring, continue to stir for 10min, and then Let stand for 2h. After filtering, washing, and drying at 60°C for 12 hours, 5.3 g of basic copper nitrate was obtained, with a yield of 72%. The shape of the product was flower-like, and the average particle size was 6 μm. The scanning electron micrographs and XRD patterns of the product are as follows: figure 1 , figure 2 shown.

Embodiment 2

[0026] Example 2: Prepare 40ml of copper nitrate aqueous solution with a concentration of 0.75mol / L at normal temperature, add 30mL of 1,3-propylenediamine aqueous solution with a concentration of 0.008mol / L to it under stirring, continue to stir for 10min, and then Let stand for 2h. Filtrate, wash, and then dry at 60°C for 12 hours to obtain 4.8 g of basic copper nitrate, with a yield of 66%. The product has a flaky appearance and an average particle size of 2 μm. The scanning electron microscope photograph of the product is as image 3 shown.

Embodiment 3

[0027] Example 3: Prepare 40 ml of copper nitrate aqueous solution with a concentration of 0.75 mol / L at room temperature, add 30 mL of 1,3-propylenediamine aqueous solution with a concentration of 0.004 mol / L to it under stirring, continue stirring for 10 min, and then Let stand for 2h. Filter, wash, and then dry at 60°C for 12 hours to obtain 4.2 g of basic copper nitrate microspheres, with a yield of 58%. The product has a flake shape and an average particle size of 10 μm. The transmission electron microscope pictures of the product are as follows: Figure 4 shown.

Abstract

The invention discloses a preparation method of basic copper nitrate, which comprises the following steps: (1) reacting an aqueous solution of copper nitrate with an aqueous solution of amine compounds at 0-40°C; The reaction mixture is allowed to stand at 10-70°C; (3) filter, wash and dry the filter cake. Wherein, the amine compound is a compound in which one or more hydrogen atoms in the hydrocarbon compound molecule are replaced by -NH2. The preparation method of the invention has the advantages of simple process, short process, mild conditions, high yield, low cost and stable product properties, and the regulation and control of the morphology and particle size of the basic copper nitrate can also be realized by controlling the condition parameters.
