Embodiment Construction

[0013] Such as figure 1 Shown, the preparation method of basic copper carbonate of the present invention comprises the following processing steps:

[0014] Stir the solid state of basic copper salt (including basic copper nitrate or basic copper sulfate or basic copper chloride or copper hydroxide) or copper hydroxide with water in a reactor to form a slurry; add the solid to the reactor Sodium bicarbonate is used for solid-state reaction, and the temperature is controlled between 20°C and 140°C;

[0015] Among them, the chemical reaction formula is:

[0016]

[0017]

[0018]

[0019]

[0020]

[0021]

[0022] After the conversion is determined, put down the basic copper carbonate slurry, press filter or suction filter and wash up to the standard, and then dry to obtain the basic copper carbonate finished product.

[0023] In the above-mentioned reactions, the raw material basic copper chloride is very rich. Since my country is a big producer of electroni...

Abstract

The invention discloses a preparation method of basic cupric carbonate, which comprises the following steps: step 1, stirring the solid basic cupric carbonate or cupric hydroxide and water into a paste shape in a reactor; step 2, adding solid sodium bicarbonate in the reactor to carry out solid state reaction and controlling the temperature to be between 20 DEG C and 140 DEG C; and step 3, after the completion of measurement and conversion, firstly preparing the wet basic cupric carbonate and then preparing the finished wet basic cupric carbonate after the wet basic cupric carbonate are subjected to solid-liquid separation, and washed and dried. The invention has the advantages of high purity, low cost and less amount of waste water produced.

Description

technical field [0001] The invention relates to the field of chemical production, in particular to a preparation method of basic copper carbonate. Background technique [0002] Basic copper carbonate is an important catalyst, chemical raw material and wood preservative raw material. At present, the synthesis method of basic copper carbonate is mainly to use copper sulfate, copper chloride or copper nitrate in dissolved state with sodium carbonate or sodium bicarbonate solution Synthesis produces basic copper carbonate. Because this process is synthesized in a solution state, the volume of the solution is large, because the synthesis needs to be heated to a higher temperature, so the energy consumption is large, the amount of waste water produced is large, and the concentration of sodium chloride in the aqueous solution is produced during the synthesis. Higher, so it is not easy to clean and separate the sodium chloride in the product, and the amount of washing water used is...
