Before we answer the question concerning methods of the synthesis of Copper Chloride Dihydrate in this article, we should note that copper chloride can be bivalent, with the former CuCl, and monovalent, with the formula CuCl. Naturally, because of their different quantitative composition, they have different properties and fields of application. Therefore, methods for the synthesis of these substances also differs.
In natural conditions, this compound is encountered in the form of the rare mineral eriochalcite (the chemical composition of the crystalline hydrate CuCl·2HO crystals of blue color). As bivalent copper chloride has important practical significance, the mineral found in nature is not sufficient to satisfy the demand for it, and for this reason, numerous methods for the artificial synthesis of this substance have been developed.
The main industrial method of synthesis of bivalent copper chloride is the reaction of the chlorination of copper sulfide at a high temperature (300-400 °C). The equation is:CuS + Cl = CuCl + S.An alternative method for the synthesis of bivalent copper chloride is chloridizing roasting (at a temperature of at least 500 °C):CuS + 2NaCl + 2O = CuCl + Na-SO.
The above reactions require specialized equipment and strict safety measures, for this reason, they are only used in the industry. However, copper chloride is frequently used in various types of work in the laboratory, so we should know how this substance can be obtained in the laboratory.
