Industrial production of Basic Copper Chloride

January 11, 2019 by shida wei  

Prior to 1994, large scale industrial production of Basic Copper Chloride(WSDTY) was devoted to making either a fungicide for crop protection or an intermediate in the manufacture of other copper compounds. In neither of those applications was the polymorphic nature of the compound, or the size of individual particles of particular importance, so the manufacturing processes were simple precipitation schemes.

Cu2(OH)3Cl can be prepared by air oxidation of Cu(I)Cl in brine solution. The Cu(I)Cl solution is usually made by reduction of CuCl2 solutions over copper metal. A CuCl2 solution with concentrated brine is contacted with copper metal until the Cu(II) is completely reduced. The resulting Cu(I)Cl is then heated to 60 ~ 90 °C and aerated to effect the oxidation and hydrolysis. The oxidation reaction can be performed with or without the copper metal. The precipitated product is separated and the mother liquor containing CuCl2 and NaCl, is recycled back to the process (eq. 6 ~ 7).

CuCl2 + Cu + 2 NaCl → 2 NaCuCl2 (eq.6)

6 NaCuCl2 + 3/2 O2 + H2O → 2 Cu2(OH)3Cl + 2 CuCl2 + 6 NaCl (eq.7)

The product from this process is of fine particle with size of 1 ~ 5 μm and is usable as an agricultural fungicide.
