| titleOfInvention | Process for converting monovalent thallium compounds to trivalent thallium compounds |
| abstract | 1,100,806. Trivalent thallium compounds. TEIJIN Ltd. 26 April, 1965 [1 May, 1964; 19 Jan., 1965 (2)], No. 17535/65. Heading C1A. Monovalent thallium compounds are converted to trivalent thallium compounds by contacting the monovalent thallium compounds at least partially dissolved in an acidic aqueous medium containing chloride and/or bromide ions, with oxygen and metal ion which is oxidizable with oxygen from a lower to a higher valency state in the medium. Suitable metals are Cu, Fe, Hg, Cr, Mn, Co, Ni, and they may be added in the form of any compound which can release the metal ion, and may be in the low or high valency state at the time of addition. The aqueous medium preferably has a pH of at most 6 and may be water or mixtures of water and methanol, ethanol, glycols or acetone. To ensure the presence of chloride and/or bromide ions HCl, HBr, or the chlorides and bromides of alkali metals or alkaline earth metals may be added. The oxygen source may be air, molecular oxygen, nascent oxygen, H 2 O 2 , ozone or peroxides. The monovalent thallium may be obtained as the by-product of the oxidation of olefins to glycols using trivalent thallium for which reaction the product Tl (III) may be used. |
