Product Description

  Introduction to Anhydrous Magnesium Sulfate  

Anhydrous magnesium sulfate, commonly known by its chemical formula MgSO4, is an inorganic compound that plays a pivotal role in various industries, scientific research, and everyday applications. Derived from magnesium, sulfur, and oxygen, this odorless, white crystalline solid is renowned for its hygroscopic nature and versatile properties. In this article, we will delve into its chemical structure, production methods, physical and chemical properties, applications across different fields, safety considerations, and environmental impact.  


Chemical Structure and Nomenclature  
Magnesium sulfate is an ionic compound composed of magnesium cations (Mg2+) and sulfate anions (SO42-), held together by strong electrostatic forces. The anhydrous form, as the name suggests, contains no water molecules in its crystal lattice, distinguishing it from its hydrated counterparts like epsomite (MgSO4·7H2O), which has seven water molecules per formula unit. This structural difference significantly impacts their physical properties, such as solubility and thermal behavior.  

The compound's systematic name is magnesium sulfate, but it is often referred to as "anhydrous magnesium sulfate" to emphasize the absence of water. In industrial contexts, it may also be called "bitter salt" due to its slightly bitter taste, though this term is more commonly associated with hydrated forms.  


Production Methods  
Anhydrous magnesium sulfate is primarily produced through two main methods:  

1. Dehydration of Hydrated Forms:  
   The most common route involves heating hydrated magnesium sulfate, such as the heptahydrate (MgSO4·7H2O), to remove water molecules. This process, known as dehydration, is typically carried out at elevated temperatures (e.g., 200-300°C) in a controlled environment to prevent further decomposition.
   This method is widely used in laboratories and industries due to the abundance of hydrated magnesium sulfate deposits, such as those found in natural brines or mineral sources.  

2. Chemical Synthesis:  
   Anhydrous MgSO4 can also be synthesized by reacting magnesium oxide (MgO), magnesium hydroxide (Mg(OH)2), or magnesium carbonate (MgCO3) with sulfuric acid (H2SO4).
   This acid-base neutralization reaction yields magnesium sulfate and water, which is then evaporated to obtain the anhydrous solid. This method is preferred when high-purity products are required, such as in food applications.  
 

Anhydrous Magnesium Sulfate

Anhydrous magnesium sulfate has high purity and high stability, usually can reach more than 99%, not easy to decompose and deteriorate; It has a wide range of solubility and is easily soluble in water, ethanol and glycerol, making it easy to mix and react with other substances in printing and dyeing industries, improving production efficiency and product quality. Safe and environmentally friendly, it is a safe and non-toxic compound. 

 

Magnesium Sulfate Heptahydrate

Magnesium sulfate heptahydrate (MgSO4·7H2O), also known as sulphobitter, bitter salt, cathartic salt, Epsom salt, is a white or colorless acicular or oblique columnar crystal, odorless, cool and slightly bitter. It can be widely used in agriculture, medicine, industry and light industry, and has the characteristics of water solubility, environmental protection and safety.

 

Magnesium Sulfate Monohydrate

Magnesium sulfate monohydrate can be widely used in agriculture, industry, medicine and other fields, with high solubility, easy to be absorbed and utilized by plants, not easy to destroy soil ph value, hygroscopic. Magnesium sulfate also has high economic value.
