This substance also has practical importance, and fans of chemistry will be interested to know how this compound can be obtained. Monovalent Basic Copper Chloride was first obtained in 1666 by Robert Boyle,through the interaction of mercury(II) chloride and copper.In this reaction, the more active metal,copper,force mercury out of its salts.The equation of this reaction is:HgCl + 2Cu = 2CuCl + Hg

The second method by which we can obtain monovalent copper chloride is by the thermal breakdown of bivalent copper chloride in oxygen-free conditions.This reaction was first carried out in 1799 by Joseph Louis Proust,who separated and described the chlorides of bivalent and monovalent copper.This equation of this reaction is:2CuCl = 2CuCl + Cl

In industry, copper(I) chloride is obtained by the interaction of chlorine and an abundance of copper in a flux of copper(I) chloride at high temperature.It should be noted that chlorine is a highly toxic gas. Additionally,there are also safer laboratory methods, for example the reduction of copper(II) chloride by sulfur dioxide: 2CuCl + SO + 2HO → 2CuCl + HSO + 2HCl.Or the reduction of CuCl by ascorbic acid.Copper monochloride is used for purifying acetylene and carbon monoxide and acts as a catalyst in organic synthesis and the production of several polymers.
