Use | Iron sulfate, also known as high iron sulfate, is light yellow or white powder. Soluble in water and alcohol. The aqueous solution is acidic, and the basic salt can be formed when the dilute solution is heated to boiling. Sulfates with alkali metals or ammonium tend to form iron vanadium in the form of MFe(SO4)2 · 12H2O, such as ammonium ferric sulfate NH4Fe(SO4)2 · 12H2O, also known as Iron ammonium alum. Ferric sulfate has various hydrates containing 3, chemical book6,7,9,10,12 water, the most common being Fe2(SO4)3 · 9H2O, yellow crystals with a relative density of 2.1. After the hydrate is heated, anhydrous salt can be obtained. The hydrate can be prepared by oxidizing the ferrous salt with nitric acid or hydrogen peroxide in sulfuric acid solution. Purposes: convenient, efficient catalyst for the preparation of aromatic esters from the corresponding acid and alcohol. |
