Abstract
Przedmiotem zgłoszenia jest oksym 7,4'-dimetoksynaringeniny o worze 2 oraz sposób otrzymywania tego związku. Sposób ten polega na tym, że do substratu, którym jest 7,4'-dimetoksynaringenina o wzorze 1 dodaje się chlorowodorek hydroksyloaminy oraz bezwodny octan sodu w stosunku molowym co najmniej 1:1,5:1,5 oraz minimalną ilość alkoholu, co stanowi mieszaninę reakcyjną, którą zabezpiecza się przed dostępem światła i pozostawia w temperaturze od 35°C do 45°C na okres od 40 do 50 godzin przy ciągłym mieszaniu, po czym mieszaninę wylewa się do wody z lodem, wytrącony osad sączy się pod zmniejszonym ciśnieniem, a następnie otrzymany surowy produkt oczyszcza się.The subject of the application is 7,4'-dimethoxynaringenin oxime with bag 2 and the method of obtaining this compound. This method consists in adding hydroxylamine hydrochloride and anhydrous sodium acetate in a molar ratio of at least 1: 1.5: 1.5 and a minimum amount of alcohol to the substrate, which is 7,4'-dimethoxynaringenin of formula 1 the reaction mixture, which is protected from light and left at a temperature of 35 ° C to 45 ° C for 40 to 50 hours with continuous stirring, after which the mixture is poured into ice-water, the precipitate is filtered under reduced pressure, and then the obtained crude product is purified.
