Description
окончании прнбавлеии раствор упаривают и смешивают с ацетоиом и метанолом. Получеииый осадок раствор ют в 50 мл воды и иропускают через колонку с КУ-2-8 (Н+) с последующим элюированием водой. Элюент упаривают и осадок виовь раствор ют в смеси ацетона и метапола. Получают 22,6 (72%) продукта с т. пл. 110°С (разл.). Содержание основного вещества 99-100% (комнлексометрическое титрование).at the end of the solution, the solution is evaporated and mixed with acetome and methanol. The resulting precipitate is dissolved in 50 ml of water and sprayed through a column of KU-2-8 (H +), followed by elution with water. The eluent is evaporated and the precipitate is dissolved in a mixture of acetone and metapol. Get 22,6 (72%) of the product with so pl. 110 ° C (decomp.). Content of the main substance is 99-100% (komlexometric titration).
