Mn2O3 Pulver
?
Manganese oxide trioxide, a compound with the chemical formula Mn2O3 has a molecularweight of 157.88. Black cubic crystals. The relative density is 4.50 Water, ammonium chloride, and acetic acids are insoluble. It can be soluble in some inorganic acid. Cold hydrochloric acids can be used to dissolve it to make a brown solution. Hot dilute sulfuric or concentrated sulfuric acids will produce a red solution. MnO2 is formed from manganese oxide and MnNitrate when hot nitric, and Mn3O4 is released as O2. You can find it in two forms: a–Mn2O3 (or g–Mn2O3). The a-type of it is prepared by heating divalent manganese (nitrate, carbonate, chloride or chloride) in the air. For 78 hours at 600800, the g-type must be heated in vacuum at 500. You can use it in printing, dyeing, and oxidation processes of organic compounds and carbon monoxide.
These are some of the properties of Mn2O3 Pulver
Manganese Trioxide is a dark cubic crystal. It’s insoluble and insoluble with water, acetic acids, ammonium chloride solution, and other organic acids. When heated to 1080, it becomes Mn3O4 or O2. It can be dissolved in cold water chloric acid to a brown solution or in hot dilute sulfuric and concentrated sulfuric acids to a red solution. When heated, it will decompose into MnO2 & manganese-nitrate in hot acid. You can find it in two forms: a–Mn2O3 (g-Mn2O3) and g–Mn2O4 (both are soluble in cold hydrochloric acid).
How to prepare Mn2O3 Pulver
1. A-Mn2O3a can be prepared by further reduction, oxidation, or heat treatment of divalent manganese salts at 600 to 800 degrees Celsius. To heat manganese nuitrate hexahydrate, or pure b–MnO2, to maintain a constant weight in the air at 650°C is an option. Manganese nitrate-hexahydrate is used as the raw material. It must be heated to 190°C before it can become a solid substance. Once this has been done, it can then be pulverized at 650°C.
2. Preparation for g-Mn2O3In 350mL, 2.2g manganese sulfurate tetrahydrate were dissolved. After vigorous stirring, 34mL 3% hydrogenperoxide solution was added dropwise. 50mL 0.2mol*dm-3 wasmonia water was then added to make g-MnO (OH). To make the suspension emitting oxygen darken or black, heat for four minutes. Then filter the solution and rinse it under 1.5L of hot water. Dry the mixture in a vacuum extractor. For gMn2O3, the g-MnO (OH) was dried at 250°C for three consecutive days. You may also make gMnO2 by heating the gMnO2 at 500 degrees Celsius for 78h, under less pressure.
The use of Mn2O3 Pulver
1. The wide variety of applications for Mn2O3 are numerous. It can be used in printing or dyeing fabrics.
2. It has the ability to catalyze the reduction and oxidation organic pollutants as well organic coupling reactions.
3. You can use it as a precursor to soft magnetic material.
4. Used as a raw ingredient in the production of lithium-ion battery electrode materials.
5. It’s the main raw material for manganese compound and an intermediate product.
