Application

Antimony(III) sulfate serves a dual purpose in industrial and chemical applications. Primarily presented as a white, deliquescent powder or in lump form, it decomposes in water and exhibits hygroscopic properties with a distinctive silken sheen when crystallized as needles. This compound is typically synthesized by dissolving antimony or its derivatives, such as antimony trioxide, trisulfide, or oxychloride, in hot sulfuric acid. It is prominently used in the production of explosives and fireworks due to its reactive nature. Additionally, Antimony(III) sulfate acts as a valuable catalyst in the imino Diels-Alder reaction, facilitating the synthesis of complex organic compounds like 2-aryl-4-(2'-oxopyrrolidinyl-1')-1,2,3,4-tetrahydroquinolines through its interaction with Schiff's bases and N-vinylpyrrolidin-2-one.
