CAS 1314-32-5: Thallium oxide (Tl2O3)

Thallium(III) oxide (99.99%-Tl) PURATREM

Thallium(III) oxide (99.5%-Tl)

Thallium oxide is a white solid that is used in the production of semiconductors, glass, and ceramics. The fluorescence spectrometry technique can be used to identify thallium compounds with high accuracy and sensitivity. Thallium oxide also has an acylation reaction with fatty acids. Thallium oxide can be easily oxidized by air to form a stable oxide, which has been shown to have a thermal expansion coefficient similar to zirconia. This chemical also has properties that are very similar to those of iron oxides, such as irreversible oxidation and hydrogen bonding interactions.

Thallium (III) oxide is a white powder that is insoluble in water and hydrochloric acid, soluble in nitric acid, and melts at 200 degrees Celsius. It has a density of 3.2 g/cm3 and thermal expansion coefficient of 5.5x10-6 K-1. Thallium (III) oxide has an irreversible oxidation reaction with hydrochloric acid to form thallous chloride and hydrogen gas. It also undergoes strong absorption of ultraviolet light at wavelengths below 300 nm, which makes it useful for the detection of hydrocarbons in petroleum products. Thallium (III) oxide can be used as a catalyst for acylation reactions and exhibits hydrogen bonding interactions with organic molecules.

Thallium(III) oxide is used in organic synthesis and as an analytical reagent This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.
