Abstract

СПОСОБ ПОЛУЧЕНИЯ 8-ОКСИХИНОЛАТА МЕДИ путем взаимодействи  о-аминофенола, глицерина, серной кислоты и о-нитрофенола при 130-140 С с последующей обработкой реакционной смеси сульфатом меди и выделением целевого продукта, отличаю- щ и и с   тем, что, с целью повышени  выхода и упрощени  технологии процесса, расплавленный о-нитрофенол добавл ют порци ми по 8-10% от рассчитанного количества с интервалом времени 10 мин или непрерывно до разности между конечным и начальным потенциалами 250 MB в нагретую до 130-140 С реакционную массу, состо щую из глицерина, о-аминофенола и серной кислоты.THE METHOD OF PREPARING 8-OXYCHINOLATE COPPER by reacting o-aminophenol, glycerol, sulfuric acid and o-nitrophenol at 130-140 ° C, followed by treatment of the reaction mixture with copper sulfate and with the aim of increasing the yield and simplification of the process, the molten o-nitrophenol is added in portions of 8-10% of the calculated amount with a time interval of 10 minutes or continuously to a difference between the final and initial potentials of 250 MB in a reaction mass heated to 130-140 ° C from glyc rina, o-aminophenol and sulfuric acid.
