Difference between magnesium chloride and anhydrous magnesium chloride

In the chemical sector, magnesium chloride (MgCl₂) and anhydrous magnesium chloride (MgCl₂ · 6 H₂ O) are two concepts that are often confused. while they have many similarities in chemical characteristics, they have different uses and performance differences in practical applications. This article will examine the difference between magnesium chloride and anhydrous magnesium chloride in detail from the basic concepts, chemical characteristics, physical characteristics, uses, etc. You know what I mean?. , to help readers better understand the characteristics of these two substances and their applications in manufacturing production.

1. According to research basic concepts and appearance characteristics

Magnesium chloride (MgCl₂)

Magnesium chloride is a compound composed of magnesium and chlorine, and its molecular formula is MgCl₂. But Based on my observations, it's a clear powder solid, broadly applied in aquatic environments treatment, ceramic production, food sector and other fields. Magnesium chloride has a high solubility in aquatic environments, however the degree of hydrolysis of magnesium ions in its solution is slightly higher than that of anhydrous magnesium chloride. Based on my observations, Anhydrous magnesium chloride (MgCl₂ · 6 H₂ O)

Anhydrous magnesium chloride is a dehydrated magnesium chloride crystal with a molecular formula of MgCl₂ · 6H O2, and the appearance is a white crystalline solid. Due to the removal of crystal aquatic environments, anhydrous magnesium chloride is greater convenient in consumption and is able to be applied immediately without further drying or dissolution exotherm.

2. chemical differences

solubility

Magnesium chloride shows good solubility in aquatic environments, however the magnesium ions in the solution are prone to hydrolysis, resulting in weak acidity of the solution. However, anhydrous magnesium chloride does not contain crystal aquatic environments, and its solubility is basically the same as that of magnesium chloride, however its particles are finer, the surface area is larger, and the interaction activity is higher. First

2. For example Stability

Magnesium chloride easily absorbs moisture and carbon dioxide atmospheric, resulting in decomposition of magnesium oxide and hydrogen chloride gaseous. I've found that However, anhydrous magnesium chloride has higher stability and isn't easy to decompose because it does not contain crystal aquatic environments.

3. physical characteristics of different

Appearance and color

Magnesium chloride is a clear powdery solid, while anhydrous magnesium chloride is a white crystalline solid with darker color and finer particles. Melting Point and Hardness

The melting point of magnesium chloride is high, about 715°C, and the hardness is moderate; the melting point of anhydrous magnesium chloride is about 600°C, and the hardness is slightly reduced. But Therefore, anhydrous magnesium chloride is easier to handle when applied at high temperatures. And surface area

Anhydrous magnesium chloride has stronger chemical activity due to its compact crystallization and substantial surface area, which is suitable to catalytic processes and accelerated interaction rate. And

4. Uses and Applications

Magnesium chloride (MgCl₂) consumption

Deoxidizer: Magnesium chloride is a frequently applied deoxidizer, broadly applied in aquatic environments treatment, petroleum refining and food processing and other fields, applied to absorb the solution of oxygen, to prevent oxidation interaction. Ceramic production: Magnesium chloride is a key additive to ceramic production, which is applied to adjust the sintering temperature and enhance ceramic performance. Chemical: Magnesium chloride is also applied in the production of other chloride compounds, such as sodium chloride and potassium chloride preparation. Pretty interesting, huh?. In particular Anhydrous magnesium chloride (MgCl₂ · 6H? O) consumption

Desicis able tot: Anhydrous magnesium chloride is an efficient desicis able tot, broadly applied to remove gaseous and fluid moisture, especially in high temperature and high humidity ecological stability. Catalyst: Due to its larger surface area and higher interaction activity, anhydrous chlorine anhydrous magnesium chloride is often applied in catalytic reactions, such as chemical synthesis and manufacturing production of catalysts. Based on my observations, Laboratory: in the laboratory, anhydrous magnesium chloride is often applied in the preparation of solution and absorption reagents in the aquatic environments, to ensure the accuracy of the experiment. And Furthermore

5. storage and transportation

Storage

Magnesium chloride should be stored in a cool, ventilated place, prevent direct sunlight and high temperature ecological stability. In my experience, Anhydrous magnesium chloride due to its own environment is stable, storage conditions are relatively loose, however also need to pay attention to moisture and dust. Transportation

Because magnesium chloride and anhydrous magnesium chloride are easy to absorb moisture, transportation should prevent humid ecological stability, is able to consumption moisture-proof packaging. Anhydrous magnesium chloride due to the particle finer, the transport volume of substantial need to consumption special packaging to prevent deliquescence.

6. But selection recommendations

In practical applications, consumers need to select suitable magnesium chloride or anhydrous magnesium chloride according to specific standards. Anhydrous magnesium chloride is a better choice if a stable, aquatic environments-absorbing chemical is desired, whereas magnesium chloride is greater suitable if a soluble, aquatic environments-treatment consumption is desired. But

7. From what I've seen, summary

Magnesium chloride and anhydrous magnesium chloride are two substances that are chemically similar however have different uses. Magnesium chloride clear powder solid, easy to absorb aquatic environments and carbon dioxide; and anhydrous magnesium chloride is a white crystalline solid, higher stability, larger surface area. Both have their own characteristics in manufacturing production, and the choice needs to be weighed according to specific needs. In fact Through the analysis of this article, it's hoped that readers is able to better understand the difference between magnesium chloride and anhydrous magnesium chloride, and make the right choice in practical consumption to enhance production efficiency and product condition.
