Embodiment Construction

[0013] The preparation method of cuprous oxide of the present invention comprises the following processing steps:

[0014] Step 1. Synthesis: adjust 100Kg of copper-containing compound in terms of copper to acidic conditions, add 92Kg of sodium chloride, then add 100Kg of metal copper or other reducing agents in an equivalent amount, heat and react under stirring conditions, and generate chlorine by hydrolysis Cuprous oxide;

[0015] Step 2, get 100Kg cuprous chloride (in terms of dry product) and add sodium hydroxide (in terms of 100%) 40Kg and water stirring reaction to generate cuprous oxide, wherein the reaction equation is:

[0016] CuSO 4

[0017] CuCl 2 +Cu(reducing agent)+NaCL→CuCL;

[0018] Cu(NO 3 ) 2

[0019] CuCl 2 3Cu(OH) 2 ·XH 2 O(X=1 / 2, 1, 2)

[0020] CuCl+NaOH→Cu 2 O;

Abstract

The invention discloses a cuprous oxide preparation method. The cuprous oxide preparation method comprises that copper-containing compounds comprising copper sulphate, cupric chloride, cupric nitrate, copper hydroxide mud, copper oxychloride, etc., undergo a reduction reaction with a reductant such as Cu to generate cuprous chloride; the cuprous chloride undergoes a reaction with sodium hydroxide to generate cuprous oxide; and the cuprous oxide is dried to form cuprous oxide products. Through the method of the invention, a production speed and an output of cuprous oxide products are increased and the production cost of the cuprous oxide products is reduced. The cuprous oxide products have the advantages of high product purity of 99%, no side-reaction, small particle size, low proportion and big specific surface area, and raw materials of the cuprous oxide products can be obtained easily.

Description

technical field [0001] The invention relates to the field of chemical production, in particular to a method for preparing cuprous oxide. Background technique [0002] At present, the preparation methods of cuprous oxide are high-temperature fire method and electrolysis method. The high-temperature fire method is obtained by reacting copper oxide and metal under copper powder airtight conditions. Soluble copper is obtained by electrolysis, but the cuprous oxide produced by these two methods is hard, heavy, and the particles are uneven, which is inconvenient to use in agriculture, paint and other occasions that require fine particles. And the required cost of the cuprous oxide that this kind of method makes is high, and raw material is difficult to obtain. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a method for preparing cuprous oxide with fast production speed, high...
