Abstract
290,174. I. G. Farbenindustrie Akt.- Ges. May 6, 1927, [Convention date]. Titanium dioxide; double salts. - Titanium cres are treated with sulphuric acid and the titanium then brought into solution as a double salt by treatment with an alkali salt such as sodium, potassium, or ammonium sulphate. Preferably, the solution step is effected under heat and the proportions so chosen that a saturated solution is obtained, from which, after filtration, the double salt may be crystallized out. The crystals may be washed with a saturated solution of alkali sulphate or be re-crystallized from dilute sulphuric acid to free them from iron. From a solution in dilute surphuric acid or a suspension in water of the double salt, titanic acid may be obtained by hydrolysis, if desired under pressure. The mother-liquor containing sulphuric acid and alkali sulphate may be used in the solution step of the process.
