| THALLIUM(I) FLUORIDE Usage And Synthesis |
| Preparation | Thallium fluoride is prepared by reacting thallium carbonate with hydrofluoric acid. Also, the compound can be made by reacting thallium metal with fluorine.
| | Chemical Properties | white powder(s); ortho-rhomb; hard, shiny crystal(s); can deliquescent, e.g., if breathed upon, however reverts to anhydrous form in dry air; not typically hygroscopic; enthalpy of fusion 14.00kJ/mol [MER06] [STR93] [CRC10] | | Physical properties | Hard shiny crystals; orthorhombic structure; density 8.23 g/cm3 at 4°C; melts at 327°C; begins to sublime at 300°C; vaporizes at 655°C; very soluble in water, 78.6 g/100mL at 15°C; decomposes in hot water; slightly soluble in alcohol. | | Uses | Thallium(I) fluoride is used as chemical reagents, fine chemicals, pharmaceutical research and development. | | Uses | In the preparation of fluoro esters. | | Hazard | Highly toxic (See Thallium). | | Safety Profile | Poison by ingestion. When heated to decomposition it emits very toxic fumes of Fand T1. See also THALLIUM COMPOUNDS and FLUORIDES. |
