1.3 Synthetic Route
After removing impurities, dry copper powder is mixed with copper oxide, and sent to the calcined furnace to be heated to 800~900 °C to calcide into cuprous oxide. After taking out, the mechanical impurities are absorbed by magnets, and then crushed to 325 mesh to obtain a finished product of cuprous oxide. If copper sulfate is used as raw material, the copper in copper sulfate is first reduced with iron, and the subsequent reaction steps are the same as those using copper powder as raw material. 1317-39-1 preparation 2. Glucose reduction method mixes copper sulfate solution with glucose and adds sodium hydroxide solution for reaction to generate cuprous oxide, which is filtered, rinsed, dried and crushed to obtain cuprous oxide products.
