Description
Предметом изобретени вл етс способ очистки водных растворов витамина Bi2, получаемых после десорбции витамина с активированного угл .The subject of the invention is a method for purifying aqueous solutions of vitamin Bi2 obtained after desorption of vitamin C from activated carbon.
Предлагаемый способ позвол ет ускорить и упростить очистку водных растворов витамина Bi2.The proposed method allows to speed up and simplify the purification of aqueous solutions of vitamin Bi2.
Особенность способа заключаетс в том, что водные растворы витамина Bi2, получаемые после десорбции витамина с активированного угл , подвергают последовательной обработке бензиловым спиртом, гидроокисью цинка и смесью крезола с четыреххлористым углеродом.The particularity of the method is that aqueous solutions of vitamin Bi2 obtained after desorption of vitamin C from activated carbon are subjected to sequential treatment with benzyl alcohol, zinc hydroxide and a mixture of cresol with carbon tetrachloride.
П р и м е р. В 1л элюата с содержанием 250 113 витамина Bi2 добавл ют 0,2%-ный NaCN и NaCl и затем витамин экстрагируют 400 мл бензилового спирта. Полученный экстракт промывают насыщенным раствором поваренной соли, и витамин В12 перевод т в 250 мл воды.PRI me R. In 1 liter of eluate containing 250,113 vitamin Bi2, 0.2% NaCN and NaCl are added, and then the vitamin is extracted with 400 ml of benzyl alcohol. The extract obtained is washed with a saturated solution of common salt, and vitamin B12 is transferred to 250 ml of water.
К водному раствору добавл ют при подкисленин 25 г ацетата цинка и затем довод т 15%-ной NaOH рН до 8,5. Осадок после фильтрации промывают 200 мл воды.With acidification, 25 g of zinc acetate is added to the aqueous solution and then the pH is adjusted to 8.5 with 15% NaOH. The precipitate after filtration is washed with 200 ml of water.
Из 500 мл полученного раствора витамин В12 экстрагируют малыми порци ми смеси крезола с четыреххлористым углеродом (. 1); всего получаетс 50 мл экстракта. После добавлени 65 мл четыреххлористого углерода и 40 мл бутилового спирта витамин В12 перевод т в 20 мл воды.From 500 ml of the obtained solution, vitamin B12 is extracted with small portions of a mixture of cresol with carbon tetrachloride (1); a total of 50 ml of extract is obtained. After adding 65 ml of carbon tetrachloride and 40 ml of butyl alcohol, vitamin B12 is transferred to 20 ml of water.
После промывки эфиром к водному раствору витамина добавл ют 60 мл ацетона, и раствор пропускают через колонку с АЬОз (диаметр 3 см, высота 40 см).After washing with ether, 60 ml of acetone are added to the aqueous solution of the vitamin, and the solution is passed through a column of HOC3 (diameter 3 cm, height 40 cm).
К 80 мл ркоокрашенной фракции улюата добавл ют 320 мл ацетона, и раствор став т на холод дл кристаллизации .320 ml of acetone was added to 80 ml of the colored fraction of the uluate, and the solution was allowed to cool for crystallization.
Получают 168 мг кристаллического витамина Bi2, или 67% от начального содержани . Чистота кристаллов 76%, т. е. удовлетвор ет техническим услови м на фармако|НлЧ168 mg of crystalline vitamin Bi2, or 67% of the initial content, are obtained. The purity of the crystals is 76%, i.e., it satisfies the specifications for pharmaco | NlCh

Предмет изобретени Subject invention
Способ очистки водных растворов витамина Bi2, получаемых после десорбцрп витамина с активированного угл , о т л и ч а ю щ и и с тем, что, с целью ускорени и упрощени способа , примен ют последовательную обработку бензилозым спиртом, гидроокисью цинка и смесью крезола с четыреххлористым углеродом.The method of purification of aqueous solutions of vitamin Bi2, obtained after desorption of vitamin C from activated carbon, is needed so that, in order to speed up and simplify the process, sequential treatment with benzyl alcohol, zinc hydroxide and cresol mixture carbon tetrachloride.
