Thallous acetate or thallium(I) acetate is a salt of thallium and acetate with the chemical formula TlCH 3 COO. It is used in microbiology as a selective growth medium . [ 3 ] It is poisonous.
Thallium(I) sulfate is soluble in water and its toxic effects are derived from the thallium(I) cation. The mean lethal dose of thallium(I) sulfate for an adult is about 1 gram. Since thallium(I) sulfate is a simple powder with indistinctive properties, it can easily be mistaken for more innocuous chemicals.
Thallium(III) acetate is the acetate salt of thallium, with the chemical formula Tl(CH 3 COO) 3. As a selective culture medium in microbiology, [1] thallium acetate is toxic, [2] but it can also be used as a hair loss agent. Koremlu, a depilatory that contained the rat poison Thallium acetate was widely marketed during th 1930s.
The National Institute for Occupational Safety and Health (NIOSH) also set a recommended exposure limit (REL) of 0.1 mg/m 2 skin exposure over an eight-hour workday. At levels of 15 mg/m 2, thallium is immediately dangerous to life and health. [71] Contact with skin is dangerous, and adequate ventilation is necessary when melting this metal.
Contact with skin is dangerous and adequate ventilation should be provided when melting this metal. [2] Many thallium compounds are highly soluble in water and are readily absorbed through the skin. [3] Exposure to them should not exceed 0.1 mg per m 2 of skin in an 8 hour time-weighted average (40-hour working week).
Thallium(I) hydroxide is obtained from the decomposition of thallium(I) ethoxide in water. [3] CH 3 CH 2 OTl + H 2 O → TlOH + CH 3 CH 2 OH. This can also be done by direct reaction of thallium with ethanol and oxygen gas. 4 Tl + 2 CH 3 CH 2 OH + O 2 → 2 CH 3 CH 2 OTl + 2 TlOH. Another method is the reaction between thallium(I) sulfate and ...
Thallium(I) nitrate, also known as thallous nitrate, is a thallium compound with the formula Tl NO 3. It is a colorless and highly toxic salt. It is a colorless and highly toxic salt. Preparation
Thallium(I) bromide is a chemical compound of thallium and bromine with a chemical formula TlBr. This salt is used in room-temperature detectors of X-rays, gamma-rays and blue light, as well as in near-infrared optics. It is a semiconductor with a band gap of 2.68 eV. [7]
