Abstract
Procedeul conform inventiei, consta în tratarea unei rasini schimbatoare de anioni cu TiCl4 în acid clorhidric de concentratie 8,8% timp de 15 min pîna la 7h, filtrarea rasinii si spalarea ei cu acid clorhidric cu aceeasi concentratie. Hidroliza anionului complex de titan retinut pe rasina se poate realiza pe trei cai. Se obtin rasini macroporoase puternic anionice ca de exemplu Vionit AT-14; cu 50...70 mg Ti/g si slab anionic, ca de exemplu MP 7080, cu 25...30 mg Ti/g de rasini.The process according to the invention consists in treating an anion-exchange resin with TiCl4 in 8.8% hydrochloric acid for 15 minutes to 7 hours, filtering the resin and washing it with the same concentration of hydrochloric acid. The hydrolysis of the complex titanium anion retained on the resin can be achieved in three ways. Strong anionic macroporous resins such as Vionit AT-14 are obtained; with 50 ... 70 mg Ti / g and low anionic, such as MP 7080, with 25 ... 30 mg Ti / g of resins.
