1. Chemical industry
Desiccant: Anhydrous magnesium sulfate has strong hygroscopicity and is commonly used for drying organic solvents and gases. It can effectively remove moisture from solvents, such as being commonly used in organic synthesis reactions to dry solvents.
Catalyst or catalyst carrier: In certain chemical reactions, anhydrous magnesium sulfate is also used as a catalyst or catalyst carrier. For example, it plays an important role in certain esterification reactions and organic synthesis processes.
2. Other uses
Air drying: In some special applications, anhydrous magnesium sulfate can be used for air drying, especially in laboratories or special work environments that require low humidity.
Preservative: Anhydrous magnesium sulfate can be used as a preservative, especially in certain plant protection products.
