Melting point 1235 ° C Relative density 6.0 Solubility Insoluble in water and alcohol, soluble in hydrochloric acid, ammonium chloride, ammonia, slightly soluble in nitric acid. Dissolved in hydrochloric acid to form white cuprous chloride crystal powder. It can be dissolved in a solution such as concentrated alkali or ferric chloride.
Cuprous oxide product use
[Use 1] Used as a ship bottom coating, pesticide fungicide, glaze, used in cuprous oxide rectifiers, photovoltaic cells, electroplating, and production of copper salts, etc.
[Use 2] used as analytical reagents and fungicides
[Use 3] It is used to make antifouling paint on the bottom of the ship (used to kill low-grade marine animals), insecticides, and various copper salts, analytical reagents, and red glass. Also used for rectification plating in the electrical industry. Also used as a coloring agent for ceramics and enamels.
[Use 4] Cuprous oxide
[1317-39-1] is used to prepare antifouling paint on the bottom of the ship to kill low-grade marine animals and protect the hull and bottom of the ship below the horizontal line. Used as a colorant for ceramics and enamels, as a stain for red glass. It is also used as a catalyst for the hydrogenation synthesis of methyl chloride and silicon powder in the production of silicone resin. In addition, it is also used in the manufacture of various copper salts, analytical reagents, bactericides and in rectification plating in the electrical industry.
[Use 5] When measuring nitrogen in azo compounds as a reducing agent, red glaze, electroplating, fungicide, red glass, bottom paint, plant seed sterilization, catalyst.
Storage and transportation characteristics of cuprous oxide
Warehouse low temperature, ventilated, dry; separate from food materials
Preparation method of cuprous oxide
Its Cu+CuO→Cu2O
CuSO4+2NaOH→Na2SO4+Cu(OH)2↓
2Cu(OH)2+CH2OH(CHOH)4CHO→Cu2O↓+2H2O+CH20H(CHOH)4COOH
Cathodic reaction: 2H++2e→H2O↑
Anode reaction: Cu–2e→Cu+
2Cu++2C1-→Cu2C12
Cu2C12+2NaOH→Cu2O↓+H2O+2NaCl
First aid measures for cuprous oxide pesticide poisoning
[Toxic symptoms] Ingestion caused acute poisoning, manifested as headache, dizziness, fatigue, blue mucosa, metallic taste in the mouth, bleeding gums, blue tongue, diarrhea, abdominal cramps, black stools, severe coma, sputum , blood pressure drops and so on.
[First-aid treatment] Oral poisoning, immediately induce vomiting, gastric lavage. The antidote is disodium edetate and is treated with symptomatic treatment.
[Precautions] Mixture with Chunreimycin is sensitive to young leaves of apples, grapes, soybeans and alfalfa, so be sure to pay attention to the concentration. It is advisable to spray after 4 pm. Cannot be mixed with acid and calcium polysulfide
