Magnesium chloride is a common inorganic salt with a variety of properties and uses. The properties and uses of magnesium chloride are detailed below.
1. Properties of magnesium chloride
Magnesium chloride is a white or colorless crystalline powder, soluble in water, dissolved in water without hydrolysis, as a strong acidic solution. At room temperature, magnesium chloride is easily oxidized, but it does not decompose easily when heated. Magnesium chloride has a relatively low freezing point, so it is often used as a refrigerant. In addition, magnesium chloride is also a salt, so it has the general properties of salts, such as it can react with alkali to form magnesium hydroxide precipitation, and can react with metal ions to form corresponding metal chlorides.
Second, the use of magnesium chloride
1.Industrial use
Magnesium chloride is widely used in industry to make a variety of materials, such as:
It is used to make magnesium metal, which can be obtained by electrolytic molten magnesium chloride.
Used in the manufacture of neoprene, magnesium chloride can be used as a coagulant for neoprene to improve the quality and yield of rubber.
Used in the manufacture of silicon compounds, magnesium chloride can react with silicon compounds to prepare a variety of silicon compounds, such as silicone, silicon ether, etc.
It is used in the manufacture of other inorganic salts, such as magnesium nitrate, magnesium sulfate, etc.
2.Food uses
In the food industry, magnesium chloride is used as a preservative, stabilizer, and coagulant. For example, in the production of tofu, the addition of magnesium chloride can make the bean juice coagulate into tofu. In addition, magnesium chloride is also used in the production of ice cream and other foods, acting as a stabilizer. In winemaking, magnesium chloride can be used as an acidity regulator. However, it should be noted that excessive use of magnesium chloride can cause harm to the human body, so the amount of magnesium chloride in food should be strictly controlled.
3.Pharmaceutical field
In the pharmaceutical field, magnesium chloride also has a wide range of applications.
4.Other uses
In addition to the above uses, magnesium chloride is also widely used in construction, roads, bridges and other engineering fields. In the construction industry, magnesium chloride can be used as a component of cement mixtures to improve the compressive and flexural strength of cement. In the construction of roads and bridges, magnesium chloride can be used as an additive. In addition, magnesium chloride is also used as a snow melting agent, chemical reagent, auxiliary, etc.
In conclusion, magnesium chloride has a variety of properties and uses, and is widely used in industry, food, medicine, and other fields. However, it should be noted that the dosage and method should be strictly controlled when using magnesium chloride to avoid harm to the human body and the environment. At the same time, we should also continue to pay attention to and study other properties and uses of magnesium chloride, so as to make better use of it and contribute to the development of human society.
