Abstract
Przedmiotem zgłoszenia jest oksym 5,7,4'-trietoksynaringeniny o wzorze 2 oraz sposób wytwarzania tego związku. Sposób ten polega na tym, że do substratu, którym jest 5,7,4'-trietoksynaringenina 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 45°C do 55°C na okres od 10 do 24 godzin przy ciągłym mieszaniu, po czym mieszaninę wylewa się do wody z lodem, wytrącony osad sączy się pod zmniejszonym ciśnieniem, a następnie przemywa woda i osusza się.The subject of the application is 5,7,4'-triethoxynaringenin oxime of formula 2 and a method for preparing 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 5,7,4'-triethoxynaringenin of formula 1. which is a reaction mixture, which is protected from light and left at a temperature of 45 ° C to 55 ° C for 10 to 24 hours with continuous stirring, after which the mixture is poured into ice-water, the precipitate is filtered under reduced pressure pressure, and then washed with water and dried.
