(54) СПОСОБ ПОЛУЧЕНИЯ КАЛИФОРНИЯ В ДВУХВАЛЕНТНОМ(54) METHOD FOR OBTAINING CALIFORNIA IN DOUBLE-VALUE

СОСТОЯНИИCONDITION

Claims (1)

Изобретение относигсп к способу получени  калифорни  в новом двухвалентном состо нии, который использовать ОЛЯ его отделени  от других актинидов и их аналогов. Сущность способа состоит в том, что в сол нокислый водно-этанольный раствор трехвалентного калифорни  с концентрацией воды 1-8 моль/л и хлористого водорода О,2-7 моль/л ввод т металлический магний и трихлорид самари . Пример. К1 мл водно-эганольно го раствора трехвалентног-о калифорни , содержащего 100 мг трихлорида самари  и 3 ммоль воды, добавл ют 40 мг мапни  в виде стружки толщиной 0,1 мм и последовательно трем  порци ми добавл ют 1 мл 7 М раствора хлористого водорода в 96 о-ном этаноле. При этом треХ алентиый колкфорний восстпнаопипевтс  до двухвалентного состо ни . Из растьора его выдел ют сокристаллизацней с образующимс  дихлоридом самари . Формула изобретени  Способ получени  калифорни  в двухвалентном состо нии, отличающийс  тем, что сол нокислый водноэтанольный раствор трехвалентного кали- форни  с концентрацией воды моль/л и хлористого водорода О,2-7 моиь/л обрабатывают металлическим магнием в присутствии трихлорида самари .The invention relates to a method for producing californium in a new bivalent state, which is used by its separation from other actinides and their analogues. The essence of the method consists in the introduction of metallic magnesium and samarium trichloride into a hydrochloric acid-ethanol solution of trivalent californium with a water concentration of 1–8 mol / l and hydrogen chloride O, 2–7 mol / l. Example. K1 ml of a water-eganolic solution of trivalent-californium containing 100 mg of samarium trichloride and 3 mmol of water is added 40 mg of mapni in the form of chips 0.1 mm thick and 1 ml of 7 M hydrogen chloride solution is added in three portions 96 o. Ethanol. In this case, the three alentiy colkforium is restored to a bivalent state. It is isolated from the raster by cocrystallization with samarium dichloride formed. Claims of Invention A method of producing californium in a bivalent state, characterized in that a hydroxylate water-ethanol solution of trivalent caliphorni with a water concentration of mol / l and hydrogen chloride O, 2-7 my / l is treated with metallic magnesium in the presence of samarium trichloride.
