Botallackite preparation method and uses thereof

Abstract

A method for preparation and use of sloping atacamite belonging to the area of fine chemical engineering, the characters of which consist in the process steps as follows: preheating the ammonium chloride solution, copper chloride solution and ammonial solution to 65-100 degree centigrade separately; the concentration of ammonium chloride solution is 5-25%, the concentration of copper in copper chloride solution is 100-200g / L, the content of ammonial in ammonial solution is 5-20%; adding ammonium chloride solution to reactor equipped agitating device, at the same time, adding copper chloride solution and ammonial solution with the mole proportion of 2:3 to undergo neutralizing reaction during agitation for deposit of sloping atacamite. The invention has simple process, high reaction sensitivity and low cost; the sloping atacamite produced in the method has high yield, excellent quality, stable property and is suitable for mass production. So the sloping atacamite can be used for feed addictive on a large scale for the stable property

Description

Technical field: [0001] The invention relates to a preparation method and application of botallackite, belonging to the technical field of fine chemicals. Background technique: [0002] At present, basic copper chloride has been widely used abroad as an animal copper nutritional additive, and it has gradually been recognized by people of insight in China in the past two years. [0003] It has been found that basic copper chloride has four isomers in nature: orthorhombic atacamite, triclinic paratacamite, and monoclinic Botallackite (botallackite) and monoclinic clinoatacamite. Among them, chloratackite and paratacamite are widely distributed, and chloratackite is very rare due to its poor stability, and usually exists as an associated ore of chloratackite and paratacamite. [0004] The present research on the synthesis conditions and stability of Chloratackite, Paratacamite and Botallackite has found that if the reaction temperature and reaction time are strictly controlle...

Problems solved by technology

[0006] The Chinese patent CN1069188C of U.S. traditional environmental service company has introduced a kind of method utilizing printed circuit board copper chloride etching waste liquid to produce feed grade basic copper chloride, but there are two defects in its production process: 1. due to basic chlorination The synthesis reaction of copper is carried out at normal temperature. In order to ensure sufficient reaction, the residence time can be as long as 8 hours, and the production efficiency is too low; ②The synthesis and precipitation separation of basic copper chloride are carried out in two different containers, and the production efficiency is further reduced

In addition, Chinese patent CN1230092C describes another method for producing feed-grade crystalline basic copper chloride, but there are also problems such as cumbersome reaction process, long time consumption, low production efficiency, and the purity and crystal structure of the product. narrative

There is also a key problem, that is, the purity of the main raw material - copper sulfate or copper sulfate ore is not stated

However, the country has strict restrictions on the content of harmful elements such as lead and arsenic in feed additives. Copper sulfate ore containing a large amount of associated heavy metal impurities is not suitable for use as raw materials; even ordinary industrial-grade copper sulfate may be mixed with a considerable amount of Harmful heavy metals must be tested before use

However, if high-purity copper sulfate is used, the production cost of basic copper chloride is bound to increase, and its final price is bound to be much higher than the price of traditional feed-grade copper sulfate. copper is very difficult
