Manganese sulphate 7785-87-7 CAS NO.7785-87-7

Manganese sulfate (chemical formula MnSO4, 151.00), the first hydrate for reddish rhombic crystal, relative density 3.50, melting point is 700 ℃, soluble in water, insoluble in ethanol.It exists in a variety of hydrates.[1]

Manganese sulfate at 850 ℃ starts to break down, because of different levels, heat can be released SO3 and SO2 or oxygen, residue with manganese dioxide or four oxidation three manganese.The crystallization of manganese sulfate hydrate when heated to 280 ℃, can lose their own water of crystallization and become anhydride.[1]

Manganese sulfuric acid is a kind of microelement that is needed for the production of fatty acid. Therefore, manganese sulfate can be applied as fertilizer to soil and can increase production.Manganese sulphate added to animal feed, has the effect of fattening.Manganese sulfate is also the raw material and analytical reagent for other manganese salts.Manganese sulfate is also used in industrial production of electrolytic manganese, dye, paper and ceramics.[1]

Because of the deliquescence, the scope of application is limited.Manganese sulfate does not ignite, it is stimulating.Inhalation, ingestion or percutaneous absorption is harmful and stimulating.Prolonged inhalation of the dust can lead to chronic manganese poisoning, with early onset of neurasthenia syndrome and neurological dysfunction, and later tremor paralysis syndrome.Harmful to the environment, the water can cause pollution.

In addition, manganese sulfuric acid is also hydrated with a hydrate of manganese sulfuric acid and manganese sulfuric acid.[2-3]

Editor of materialized nature

Anhydrous manganese sulfate is nearly orthogonal series, crystal white, 3.25 g/cm3 density, melting point 700 ℃, soluble in water.[4]

A hydrated manganese sulfate is shallow pink fine crystalline monoclinic system, density of 2.95 g/mL (25 ℃), melting point 700 ℃, boiling point 850 ℃.Constant temperature is unstable.Soluble in water, solubility 5-10 g / 100 mL (21 ℃), insoluble in ethanol.Heated to 200 ℃ above begin to lose crystal water, lose most of the water of crystallization, when about 280 ℃, 700 ℃ when the melt into anhydrous salt.850 ℃ starts to break down, due to the different conditions and emit sulphur trioxide, sulfur dioxide, oxygen, or residual black insoluble four oxidation three manganese about completely decomposed at 1150 ℃.[2]

Four hydrated manganese sulfate is translucent light rose red crystal, density of 2.107 g/mL (25 ℃), soluble in water.[3]

At 850 ℃ starts to break down, because of different levels, heat can emit sulphur trioxide, sulfur dioxide, or oxygen, residue with manganese dioxide or four oxidation three manganese.Manganese sulfate can respectively with 1,2,3,4,5,7 water of crystallization of hydrate formation, heated to 280 ℃ above, all can lose their crystallization water become anhydride.[5]

Main purpose editor

The inorganic industry is used to produce and prepare manganese salts.The coating industry is used to produce the agent and the phosphating agent of linoleic acid manganese.Agriculture is an important micronutrient fertilizer and a catalyst for plant synthesis of chlorophyll.A suitable amount of manganese sulfate solution can make a variety of economic crops grow well and increase production.[6]

The expected effect of manganese sulfuric acid was mixed with manganese sulphate solution, which can increase the 1000-grain weight and increase the yield by 10%~ 15%.

Seeds: 0.2kg of manganese sulfuric acid was dissolved in 0.9kg of pure water before seeding, then 50kg of wheat seeds were mixed.

One of the important micronutrient fertilizers can be used as a base fertilizer, which can promote crop growth and increase yield by soaking, mixing, dressing, and applying the leaf surface.In animal husbandry and feed industry, it is used as feed additive, which can lead to good development of livestock and poultry, and has the effect of fattening.It is also processing paint, ink drier;The raw material of manganese diurate solution;Synthesis of fatty acids as catalyst;In addition, it can be used in papermaking, ceramic, printing and dyeing, ore flotation;The raw materials of electrolytic manganese and raw materials for other manganese salts.It is also used for battery, smelting catalyst, analytical reagent, mordant, additive, pharmaceutical auxiliary material, etc.

It is mainly present in the granule of the pituitary, hepatic pancreas and bone, and is an integral part of many enzymes.Manganese is involved in the process of hematopoiesis in the body, promoting the oxidation of fat in cells, which can prevent atherosclerosis.Manganese deficiency can cause growth retardation, osteoporosis and motor disorders.
