13478-49-4 - Introduction
Erbium(III) sulfate, also known as Erbium trisulfate, chemical formula Er2(SO4)3. The following is a description of the nature, use, formulation and safety information of Erbium(III) sulfate:
Nature:
Erbium(III) sulfate is a solid, white crystal or powder at room temperature. It is soluble in water and the solution is acidic. Erbium(III) sulfate is stable in air and decomposes at high temperatures.
Use:
Erbium(III) sulfate is mainly used as a catalyst in industry, especially in the hydrogenation process in petroleum processing. It is an important rare earth metal compound, containing rare earth element erbium, so it can also be used in the study of rare earth storage system.
Preparation Method:
Erbium(III) sulfate can be prepared by reacting a hydrate of Erbium(III) sulfate with sulfuric acid. First, the hydrate of Erbium(III) sulfate reacts with sulfuric acid to produce Erbium(III) sulfate:
2Er2(SO4)3 · xH2O 3H2SO4 → 6Er(SO4)2 · xH2O
Then, gently heat the sulfate of Erbium(III) and evaporate the water to obtain the anhydrous Erbium(III) sulfate.
Safety Information:
The storage and handling of Erbium(III) sulfate should pay attention to safety precautions. Avoid inhaling its dust or contact with skin and eyes. Wear suitable protective gloves, glasses and a mask during operation. In case of accidental contact, rinse immediately with plenty of water and seek medical help. In addition, care should be taken to prevent contact with oxidants and combustibles to avoid fire or explosion.
