Antimonitrikloridi

Antimonitrikloridi, also known as antimony trichloride, has the chemical formula SbCl3. It is a colorless solid at room temperature, although it often appears translucent or opaque due to hydrolysis. It is soluble in water, where it readily hydrolyzes to form antimony oxychloride and hydrochloric acid. This hydrolysis can be represented by the equation SbCl3 + H2O -> SbOCl + 2HCl. Antimony trichloride is also soluble in various organic solvents such as ethanol and acetone.

Industrially, antimonitrikloridi is produced by the direct reaction of antimony metal with chlorine gas or by reacting antimony trioxide with hydrochloric acid. It finds applications as a mordant in dyeing and printing textiles, as a catalyst in organic synthesis, particularly in acylation reactions, and as a component in flame retardants. Historically, it has also been used in some pharmaceutical preparations, although this is less common now due to toxicity concerns. It is considered a corrosive substance and should be handled with appropriate safety precautions.
