Description
Целевые продукты растворимы в диметилформамиде , пиридине, диметилсульфоксиде , разбавлепных минеральных кислотах . Ограниченно растворимы в спирте, ацетоне , ацетонитриле, гор чей воде.The target products are soluble in dimethylformamide, pyridine, dimethyl sulfoxide, dilute-mineral acids. Slightly soluble in alcohol, acetone, acetonitrile, hot water.
Новые красители окрашивают шерсть и полиамидные волокна из водных красильных ванн в интенсивные зеленые тона с прекрасными колористическими характеристиками , причем при окрашивании синтетических волокон исключаетс необходимость применени диспергатора.New dyes dye wool and polyamide fibers from aqueous dye baths in intense green tones with excellent color characteristics, and dyeing synthetic fibers eliminates the need for a dispersant.
Новые внутрикомплексные соединени на основе нитрозооксихинолина позвол ют расширить цветную гамму и ассортимент отечественных красителей.New intracomplex compounds based on nitroso-oxyquinoline allow the color gamut and assortment of domestic dyes to be expanded.
Ниже приведены примеры синтеза новых внутрикомплексных соединений железа формулы (II) с производными 5-нитрозо-6-оксихинолина .Below are examples of the synthesis of new intracomplex iron compounds of formula (II) with 5-nitroso-6-hydroxyquinoline derivatives.
Пример 1. Внутрикомплексное соединение железа (11) с 5-нитрозо-6-оксихинолином.Example 1. Intra-complex compound of iron (11) with 5-nitroso-6-hydroxyquinoline.
