METHOD FOR ISOLATION OF TITANIUM ALKOXIDES Russian patent published in 1997 - IPC

Abstract RU 2076106 C1

FIELD: optics, electronics. SUBSTANCE: method is carried out by isolation of titanium alkoxides of solutions which are prepared during electrochemical dissolution of titanium in the medium of alkanol, said process takes place in the presence of lithium chloride being used as conducting additive. Complete distillation of alkanol takes place by vacuum rectification. The process takes place at temperature being lower than decomposition temperature of titanium alkoxides. Thus prepared suspension is affected by hot filtration to isolate lithium chloride, desired product being distilled of mother solution. This process is carried out under vacuum at temperature being lower than decomposition temperature of desired product and at pressure in rectification column not more 50 mm Hg. EFFECT: improves efficiency of the method. 3 cl, 6 tbl
