reduction
Restore is a chemical unit process. In the chemical reaction, the reduction reaction is the reverse process of the oxidation reaction, that is, the process of obtaining electrons, because one side of the loss of electrons, there will be another side to get electrons. Therefore, the reduction reaction is often combined with the oxidation reaction, known as the oxidation-reduction reaction. But in the field of chemical industry, the purpose is only to get the product, the oxidation process is to get the oxidation products, do not care about changes in oxidants, reduction is only concerned about the reduction of products, do not care about the reductant, so the two processes can not be put together. General industrial commonly used reducing agent hydrogen, carbon monoxide, iron, zinc powder and other easy to be oxidized and oxidized to produce harmless substances. The applications of the reduction process in industry are: ▪ Reduction of ferric oxide to iron with carbon monoxide. ▪ Nitrobenzene can be reduced to aniline in water. ...
