Thermal Decomposition Of Cuprous Chloride

Put copper powder or copper wire in a fume hood and use as little dissolved nitric acid as possible. If the solution is opaque, it needs to be filtered.
 
Put copper powder or copper wire in a fume hood and use as little dissolved nitric acid as possible. If the solution is opaque, it needs to be filtered. In addition, the sodium carbonate solution and the copper nitrate solution are mixed and boiled to produce black alkaline salt precipitation. When the solid precipitates, discard the supernatant, wash it thoroughly, filter and dry by decantation, place it on an evaporating dish, heat it under a small fire and stir it well to decompose it into Cuprous Chloride ( https://www.wsdty.com/ ).

Preparation of Cuprous Chloride by Copper Powder Oxidation Method

Taking copper ash and copper slag as raw materials, roasting them and heating them with coal gas for preliminary oxidation to remove moisture and organic impurities in the raw materials. The generated primary oxide is naturally cooled, pulverized and then subjected to secondary oxidation to obtain crude Cuprous Chloride. Add the crude Cuprous Chloride to a reactor pre-filled with 1:1 sulfuric acid, and make the liquid react under heating and stirring until the relative density of the liquid doubles, and the pH value is 2-3 at the end. The reaction produces copper sulfate solution. After clarification, under heating and stirring conditions, iron filings are added to replace copper, and then washed with hot water until there is no sulfate and iron. After centrifugal separation, drying, oxidation roasting at 450°C for 8 hours, cooling, pulverization to 100 mesh, and oxidation in an oxidation furnace to obtain Basic Copper Carbonate ( https://www.wsdty.com/ ) powder.
