Explain the difference between industrial sulfuric acid and reagent sulfuric acid

As we all know, usually in the production of enterprises, most of the sulfuric acid used in industrial sulfuric acid, and sulfuric acid we use which often contain impurities, and its purity is uncertain, there may be heavy metals, sulfur dioxide and other substances, followed by Xiaobian Learn more about the difference between industrial sulfuric acid and reagent sulfuric acid.

Raw materials for industrial sulfuric acid is generally pyrite composition FeS2 grinding it, burning in a combustion furnace to generate Fe2O3 and SO2 gas. 4FeS2 + 11O2 == 2Fe2O3 + 8SO2 (gas) SO2 Continue to oxidize to SO32SO2 + O2 in the presence of a catalyst (typically V2O5) == 2SO3SO3 Water is absorbed and sulfuric acid is produced. One can imagine how much this process may be doped with various impurities.

Reagents sulfuric acid production process and industrial sulfuric acid is not the same. It can be produced by the heating distillation of industrial sulfuric acid in a quartz vessel, which leads to the possibility that it will not be contaminated with any impurities. However, since such a method consumes more energy, it is more expensive some. Clean high purity sulfuric acid plant

Reagents High purity of sulfuric acid, impurity content is almost zero. Is designed to do chemical experiments, chemical analysis. General industrial sulfuric acid is divided into 93%, 98%, 105% three, purity is not very high, high impurity content, impurity composition is very complex, but it can be widely used in industrial applications, such as fertilizers, electroplating pickling Other industries. The use of reagent sulfuric acid has been applied to other places, the content of different components, the use will change.

Although both belong to sulfuric acid, but there is a slight difference between them, we can according to their own actual situation to choose the appropriate product.
