Description
A yellow, oily liquid with a putrid smell. Antimony pentachloride is used as a stain for materials containing hydroxyl groups such as dammar, mastic, sterols, nondrying oils, and vitamins. It reacts to form an adduct that fluoresces blue-white in ultraviolet light. Antimony pentachloride is moisture sensitive and will decompose in the presence of water or alcohols.
Synonyms and Related Terms
APC; antimony perchloride
Other Properties
Soluble in hydrochloric acid, chloroform, carbon tetrachloride. Hydrolyzes in water to form solid Sb2O5.
Maximum absorption wavelength= 430 nm; Maximum emission wavelength= 550 nm.
