(54) СПОСОБ ОЧИСТКИ ДИ-2-ЭТИЛГЕКСИЛФОСФОРНОИ КИСЛОТЫ(54) METHOD FOR CLEANING DI-2-ETHYLHYXYLPHOSPHORIC ACID
ОТ ТИТАНА (IV) ды смесью 7,5 М (2,5 об.), 2,5 М НзОг (1,5 об.) и воды (1 об.) при соотношении между органической и водной фаз-алш (О:В) , равном 1:1. Концентраци титана (IV) в водной фазе после двух промывок соответстве но равна 7,6 и 0,38 г/л. Концентраци Д2ЭГФК после экстракции титана равна 1 и. П р и М а р 2. Берут 500 мл 1н. технической Д2ЭГФК с содержанием титана (V } В г/л. Три раза промывают органическую фазусмесью 7,5 М и 2 М Н2О2ПРИ . Концентраци титана (IV) в органической фазе 2,5 г/л. Концентраци Д2ЭГФК после экстракции титана равна 1 н. . П р и М е р 3. Берут 50 мл 0,5 н. технической Д2ЭГФК, содержащей 4 г/л 54 титана (IV).. Органическую фазу промывают смесью 9,75 М Е,РО(3,25 об.), 1,25 М . ( об. воды) и воды ( 1 об.) при О:В 1:1. Концентраци титана (IV) в водной фазе 4 г/л Концентраци экстрагента после экстракции 0,5 н . П р и М е р 4. Берут 50 мл 1 н. технической Д2ЭГФК, содержащей 8г/л титана (IV) . Промывают органическую фазу 50 мл смеси 12 М и 2 М 2Pz Концентраци титана (ГУ) в водной фазе 7,95 г/л. Концентраци Д2ЭГФК после экстракции 1 н. Как видно из приведенных данных, при использовании изобретени достигаетс количественна регенераци экстрагента.FROM TITANIUM (IV) with a mixture of 7.5 M (2.5 vol.), 2.5 M HzOg (1.5 vol.) And water (1 vol.) With a ratio between the organic and aqueous phases — Alsh (O: B) equal to 1: 1. The concentration of titanium (IV) in the aqueous phase after two washes is respectively equal to 7.6 and 0.38 g / l. The concentration of D2EHPA after extraction of titanium is 1 and. Pr and M and p 2. Take 500 ml of 1N. technical D2EHPA with titanium content (V} V g / l. Three times washed with an organic phase mixture of 7.5 M and 2 M H2O2PRI. The concentration of titanium (IV) in the organic phase is 2.5 g / l. The concentration of D2EHPA after titanium extraction is 1 n PR and MER 3. Take 50 ml of 0.5N technical D2EHPP containing 4 g / l 54 of titanium (IV) .. The organic phase is washed with a mixture of 9.75 ME, PO (3.25% by volume. ), 1.25 M. (vol. Water) and water (1 vol.) At O: B 1: 1. The concentration of titanium (IV) in the aqueous phase is 4 g / l. The concentration of the extractant after extraction with 0.5 n. and Мер 4. Take 50 ml of 1N technical D2EGPK containing 8g / l of titanium (IV). 50 ml of a mixture of 12 M and 2 M 2Pz Concentration of titanium (PG) in the aqueous phase is 7.95 g / l Concentration of D2EHPA after 1N extraction is obtained. As can be seen from the above data, quantitative regeneration of the extractant is achieved.
