Manganese chloride

Manganese (II) chloride, the chemical formula is MnCl2, and the relative molecular mass is 125.84.

Also known as isopropyl titanate manganous, manganese dichloride, manganese chloride tetrahydrate. The appearance of manganese chloride hydrate is rose red monoclinic crystal; the appearance of manganese chloride hydrate is rose red crystal.

It is mainly used in the production of pharmaceutical production and concentrated feed neutralizers, analytical reagents, dyes and color pastes; die-cast aluminum and aluminum alloy profile smelters, black-brown brick and tile kiln production, and pharmaceutical industry and battery production and manufacturing; It can also be used as nutrient element fertilizer in agriculture and animal husbandry.

Manganese chloride is also known as isopropyl titanate manganous; manganese dichloride; manganese chloride tetrahydrate.

Manganese chloride can be divided according to whether it has crystal water or not: without manganese chloride water and manganese chloride tetrahydrate, and according to the amount of crystal water can be divided into: manganese chloride monohydrate, manganese chloride dihydrate, chlorine tetrahydrate Manganese chloride, manganese chloride pentahydrate, etc. It is common that there is no manganese chloride water, manganese chloride tetrahydrate and manganese chloride monohydrate. Manganese chloride without water can be divided according to its appearance: particulate or spherical without manganese chloride and powder without manganese chloride.

There are many specifications and models of manganese chloride, and the sales market has two categories of analytical purity and chemical purity. This is because there is no industry standard for manganese chloride in the initial stage. Define its specifications and models.

In March 2012, my country announced the formulation of industry standards for manganese chloride, and the defined specifications are industrial products and first-class products.

Until now, it is possible to do a good job or a more general specification that can be accepted by the Chinese and foreign markets as two specifications: industrial production grade and pharmaceutical grade. Since it is a chemical raw material, it should be matched with the proper nouns of industrial production, that is, the popular name, which is more acceptable in the industry.

Manganese chloride characteristics:

Manganese chloride hydrate:

Rose red monoclinic crystal, density is 2.01, melting point is 58℃, melting point is 119℃, it can dissolve strong electrolyte, dissolve alcohol, but not ether. It has the ability to absorb water and is easy to deliquesce. It loses one molecule of crystal water at 106°C, and loses all crystal water at 198°C to become waterless.

Without manganese chloride:

Rose red crystal. The relative density is 2.97g/cm3 and the melting point is 650℃. It increases at a temperature higher than the melting point, and the melting point is 1190°C. Soluble strong electrolyte, dissolve alcohol, but not ether. Heating in the air means that part of the gas raw water is dissolved to release hydrogen chloride gas, leaving trimanganese tetroxide. Deliquescence. Generally, dry manganese chloride tetrahydrate is heated to (200±3)℃ in an electric oven filled with N2 or rare gas, so that the crystal water is slowly removed, and the small pieces obtained by individuals are cooled in a dry place. It can be broken quickly and made in sealed packaging. The manganese carbonate powder can also be taken into the hydrogen chloride system. The scope of application is the same as that of manganese chloride. It can also be used as auxiliary solution for magnesium and aluminum alloy, moisture-proof agent and medicine. Also used for cotton weaving.

Main uses of manganese chloride:

1. Used in the production of aluminum alloy profile smelters, organic chemical fluoride catalysts, dyes and color pastes, and used in the pharmaceutical industry and batteries;

2. Nutritional supplements (manganese adjuvants), in my country, milk products are required to be 1.08~4.32mg/kg; baby foods are 1.32~5.26mg/kg;

3. Manganese chloride can be used as a conductive salt in the electroplating process. The addition of manganese chloride to the ferrous chloride iron plating aqueous solution has the effect of optimizing crystals, and it is also an antioxidant, which can inhibit the air oxidation of ferrous chloride. It is also used as a nutrient fertilizer in agriculture and animal husbandry.
